We investigated the oxidative reforming (OR) of n-C4H10 over Ni/CeO2 catalysts with different amounts of Ni loading at ambient temperature by feeding a reaction mixture. The OR of n-C4H10 was triggered rapidly over all the Ni/CeO2 catalysts reduced at 1073 K. O-2 absorption at 323 K revealed that the support was composed of CeO1.76 regardless of Ni loading after reduction. We concluded that the heat produced by spontaneous oxidation of CeO1.76 to CeO2 heated the catalysts to catalytic autoignition temperature. Among the catalysts, 1 wt% Ni/CeO2 exhibited durability against carbon deposition as well as excellent catalytic activity for OR in a cyclic activity test. (C) 2009 Elsevier B. V.

SF6 was selectively hydrolyzed to SO3 over rare earth (RE) phosphates above 800 K. CePO4 was the most active catalyst, followed by GdPO4, YbPO4, DyPO4, ErPO4, SmPO4, PrPO4, TbPO4, NdPO4, and LaPO4. The middle RE phosphates were found to be more active than the light RE phosphates, but the reason for the high activity of CePO4, which belongs to the light RE group, is not clear. The catalytic activity was independent of the specific surface area (SSA), acid amount, and acid concentration of the catalysts. RE phosphates were single-phase, and a broad inversely proportional relation was observed between the crystallite size and SSA, except in the case of CePO4. The combination of highly active AlPO4 and CePO4 creates synergetic effects in the catalytic activity and SO3 selectivity over all ranges of composition. Binary catalysts were a mixture of small crystalline AlPO4 and CePO4. The addition of Ce promoted the crystallization of AlPO4, which was controlled to about 10 nm at 10-50% Ce content. The turnover frequency for SF6 decomposition was proportional to the surface concentration of hydroxyls of binary catalysts. Therefore, synergy effects may come from the number of hydroxyl (OH) pair sites on which a bidentate intermediate of hydrolysis of SF6 may be formed by the moderate crystallization of AlPO4. The addition of Ce, Pr, or Y to AlPO4 brings about a small promotion effect for SF6 decomposition, but the addition of La, Nd > Gd > Yb diminishes the activity. The addition of Gd, Pr, or Nd greatly improved the SO3 selectivity. A linear relationship between catalytic activity and the concentration of surface hydroxyls of the catalysts supports a reaction mechanism in which two F atoms of an SF6 molecule interact with two surface hydroxyls to form a bidentate intermediate.

Nanotube-shaped precursor which is composed of layered structured sodium dodecylsulfate (SDS) calcium carbonate were obtained by titration of an aqueous solution of Na(2)CO(3) into an aqueous solution containing CaCl(2) and SDS at 333-335 K. A unit of the repetition of the precursor was about 4 nm. Nanotube-shaped composite which is composed of CaCO(3) and CaSO(4) of 100-200 nm in diameter and 0.5-2 mu m in length was obtained from nanotube-shaped precursor composed of layers of CaCO(3) and SDS by calcinations at 673 K in air. The precursor sheet composed of CaCO(3) layers on which SDS molecules attached to both side seemed to curl up and form a pipe. (C) 2008 Elsevier B.V. All rights reserved.

SF6 decomposed stably over AlPO4, CePO4, YPO4, and Zr-3(PO4)(4) at 800-1000 K, but Ca2P2O7, Mg2P2O7, and Sr2P2O7 were less active. Active catalysts crystallized during the reaction. SO3, SO2F2, and HF were obtained as major products. SO3 was selectively formed over YPO4 and Zr-3(PO4)(4), but SO2F2 formed over AlPO4 and CePO4 in a significant selectivity at lower temperatures. Decomposition activity was independent of the concentration of oxygen, but it was dependent on the concentration of water vapor, suggesting that hydrolysis is the essential reaction. Catalytic activity was independent of the acidity of the catalysts. Catalytic activity was independent of the amount of surface hydroxyls, but it was correlated with the concentration of surface hydroxyls. From an analogy of hydrolysis Of CCl2F2 on AlPO4, degradation may proceed via a similar bidentate surface intermediate, OsurfaceH center dot center dot center dot F(SF4)F center dot center dot center dot HOsurface, in which two fluorine atoms of SF6 interacted with two surface hydroxyls. AlPO4 showed a steady activity and high selectivity at 843 K for 25 h, suggesting a long catalyst life. AlF3 was significantly less active than metal phosphates. This suggests that development of the catalysts which are not transformed into metal fluorides is important.

n-C4H10 autothermal reforming over MgO-supported base metal catalysts Reviewed

Katsutoshi Sato, Katsutoshi Nagaoka, Hiroyasu Nishiguchi, Yusaku Takita

INTERNATIONAL JOURNAL OF HYDROGEN ENERGY Vol. 34 ( 1 ) page： 333 - 342 2009.1

Language：English Publishing type：Research paper (scientific journal) Publisher：PERGAMON-ELSEVIER SCIENCE LTD

We report n-C4H10 autothermal reforming over MgO-supported base metal catalysts at 723 K. Catalytic performance was investigated not only after H-2 treatment at 1073 K (reductive treatment) but also after subsequent O-2/Ar treatment at the reaction temperature (oxidative treatment) to mimic the shutdown and startup of a domestic fuel cell system. After reductive treatment, both Ni/MgO and Co/MgO exhibited high n-C4H10 conversion and hydrogen formation activity; the stability of Ni/MgO was better than that of Co/MgO. The reaction route was investigated by measuring activity at various contact times. The results revealed that n-C4H10 autothermal reforming over Ni/MgO is a multi-step reaction composed of combustion, steam reforming, water gas shift reaction, and methanation. In contrast, Cu/MgO and Fe/Mgo did not show reforming activity but cracking and combustion of n-C4H10. Ni/MgO and Co/MgO catalyzed H-2 formation even after the oxidative treatment. However, the initial activity of Co/MgO after the oxidative treatment was lower than that after the reductive treatment and a decrease in H-2 formation rate was again observed after 6 h in Co/MgO, similar to the measurements after the reductive treatment.

Anaerobic oxidation of isobutane I. Catalysis by Cu-V complex oxides Reviewed

Susumu Hikazudani, Kayo Kikutani, Katsutoshi Nagaoka, Takanori Inoue, Yusaku Takita

APPLIED CATALYSIS A-GENERAL Vol. 345 ( 1 ) page： 65 - 72 2008.7

Language：English Publishing type：Research paper (scientific journal) Publisher：ELSEVIER SCIENCE BV

The anaerobic oxidation of isobutane over complex oxide catalysts of the type CunV2Ox (n = 0, 1, 2,3, and 5) was studied. V2O5, CuV2O6, and Cu2V2O7 showed high oxidizing activity, and Cu3V2O8 and Cu5V2O10 were less active. Over the active catalysts, CO2 was selectively formed only at the beginning of the reaction, and the rate Of CO2 formation decreased with reaction time. Isobutene formation became dominant 15-30 min after the start of the reaction. The rates of CO2 and isobutene formation were lower over the less active catalysts, Cu3V2O8 and Cu5V2O10. The catalytic activity at 623 K decreased in the order V2O5 > CuV2O6, Cu2V2O7 >> Cu3V2O8, Cu5V2O10. Because CO2 formed at the beginning of the reaction, this system should be applicable for the selective formation of isobutene at appropriate reduction degrees. We concluded that CuV2O6 and Cu2V2O7 should be applicable in a thin-layer reactor, in which isobutane and oxygen are separately supplied to opposite sides of the layer; in such a reactor, the catalyst surface on the isobutane side could be kept at a certain degree of reduction. Using the rate constants for isobutane consumption over Cu2V2O7, we calculated the apparent activation energy for anaerobic oxidation of isobutane to be 87.6 kJ/mol, which agrees well with the reported value for a metal oxide catalyst. XPS analysis indicated that not V5+ but Cu2+ was reduced during the reduction of Cu2V2O7 by H-2 at 473 K. Our results indicate that selective oxidation should be achievable over complex oxides that contain highly redox-active metal ions such as Cu2+ if the reaction is carried out in a thin-layer reactor.

Language：Japanese Publishing type：Research paper (scientific journal) Publisher：ELSEVIER SCIENCE BV

The catalytic activity of MV2O6 and M2V2O7 type oxides prepared by the molten method (MM) for anaerobic oxidation of isobutane was studied in order to construct a system for the selective oxidation of isobutene using a thin layer reactor. Isobutene, CO and CO2 were formed by every catalyst tested. The activities for isobutene formation were CuV2O6 > ZnV2O6, NiV2O6, CoV2O6 > MgV2O6 > MnV2O6 >> CaV2O6. Isobutene was a major product over M2V2O7 (MM). Co2V2O7 showed the highest activity and high isobutene selectivity exceeded 90%, demonstrating that CO2V2O7 is a suitable oxide for a thin layer reactor for anaerobic oxidation of isobutane. Partial substitution of Mg by Cu in Mg2V2O7 (MM) improved the activity. It is shown by the oxidation at low O-2 concentration as 2-3% that two types of oxidations occurred simultaneously: isobutene formation by the lattice oxygen ions diffused from the bulk, and CO and CO2 formation by the oxygen species derived from molecular oxygen in the gas phase.

Language：English Publishing type：Research paper (scientific journal) Publisher：ELSEVIER SCIENCE BV

Oxidative steam reforming of n-butane over supported Ni catalysts at relatively low temperature, 723 K, is reported. Among all the supported 20 wt% Ni catalysts studied, only Ni/MgO was able to convert n-butane directly after 02 oxidation. Additionally, when the Ni/MgO was prepared from an aqueous Ni(NO3)(2) Solution with pH 7, H-2 formation rate of Ni/MgO (pH 7) at a high SV (1660 l(h center dot g)(-1)) was 2.3 times as high as that of conventional Ni/MgO. The higher activity of Ni/MgO (pH 7) was ascribed to stronger resistance against oxidation of Ni-0 due to the formation of relatively large Ni-0 particles. (c) 2007 Elsevier B.V.

The Pr promotion effect on oxygen storage capacity of Ce-Pr oxides studied using a TAP reactor Reviewed

Zhaoxia Song, Wei Liu, Hiroyasu Nishiguchi, Akihide Takami, Katsutoshi Nagaoka, Yusaku Takita

APPLIED CATALYSIS A-GENERAL Vol. 329 page： 86 - 92 2007.10

Language：Japanese Publishing type：Research paper (scientific journal) Publisher：ELSEVIER SCIENCE BV

The oxygen storage capacity including OSC, OSCC and dynamic OSC was measured for Ce-Pr oxides using a temporal analysis of products (TAP) reactor system. The exact features of reduction and re-oxidation were obtained by accurately measuring the uptake of CO and O, and the production of CO2. It was found that the reduction temperature of Ce-Pr oxides was lowered 50-100 degrees C in comparison to that of CeO2. The substitution of cerium by praseodymium in the Ce1-xPrxO2-delta oxides enhanced both OSC and OSCC. However, OSCC was much influenced by the increase of praseodymium content more than OSC. It was interpreted that the addition of Pr significantly increased the amount of oxygen migrating from bulk to surface while the migration rate of bulk oxygen was slightly accelerated. On the basis of analyses of the Cc 3d, Pr 3d and O 1s X-ray photoelectron spectra, the promotion effect of Pr on oxygen storage capacity could be attributed to the CC4+/Ce3+, Pr4+/Pr3+ redox behaviour and the enrichment of oxygen vacancies in Ce1-xPrxO2-delta.

Influence of support on catalytic behavior of nickel catalysts in oxidative steam prereforming of n-butane for fuel cell applications Reviewed

APPLIED CATALYSIS A-GENERAL Vol. 327 ( 2 ) page： 139 - 146 2007.8

Language：English Publishing type：Research paper (scientific journal) Publisher：ELSEVIER SCIENCE BV

Oxidative steam reforming of n-butane over supported Ni catalysts at relatively low temperature, 723 K, is reported. Catalytic performance was investigated not only after H, treatment at 1073 K "reductive treatment" but also after subsequent O-2/Ar treatment at the reaction temperature "oxidative treatment" to mimic the shutdown and startup of the domestic fuel cell system. After the reductive treatment, n-butane conversion attained 100%, for all the catalyst at a lower space velocity (SV) of 67 L(h g)(-1). Differences in catalytic activity were emphasized at a higher SV of 667 L(h a)(-1), and were attributed to corresponding differences in metal surface area. Since a fraction of Ni in some catalysts was oxidized during the reaction at the higher SV, the reaction at the higher SV was indicated to be kinetically more oxidative condition. Although Ni/Al2O3 was inactive at the lower SV after the oxidative treatment, n-butane conversion of the other catalysts attained 100%. In contrast, only Ni/MgO was able to convert n-butane at the higher SV after the oxidative treatment. Therefore it was revealed that nickel oxide species on the catalyst were reduced by n-butane in the reactant even under severe oxidative conditions. C) 2007 Elsevier B.V. All rights reserved.

When NaCl is added in the formation of CaCO3 from CaCl2 and Na2CO3 solutions, large CaCO3 structures with complex, overlapping plates-like shapes of high calcite composition were obtained. The addition of NaCl increased the solubility of CaCO3, which promotes the transformation of vaterite to calcite and the resulting high concentration of CaCO3 promotes crystal growth rather than nucleation.

Influence of calcination procedure on the catalytic property of sulfated zirconia Reviewed

Xuebing Li, Katsutoshi Nagaoka, Laurent J. Simon, Roberta Olindo, Johannes A. Lercher

CATALYSIS LETTERS Vol. 113 ( 1-2 ) page： 34 - 40 2007.1

Language：English Publishing type：Research paper (scientific journal) Publisher：SPRINGER

Calcination parameters, such as atmosphere, duration and catalyst bed depth have a marked influence on the catalytic and spectroscopic properties of sulfated zirconia. Sulfated zirconia calcined in nitrogen or synthetic airflow, in deep bed, exhibited comparable activity in n-butane isomerization at 373 K, which suggests that oxygen is not necessary for formation of active sites. Catalysts calcined in shallow bed are catalytically inactive. Thus, the bed depth is concluded to be crucial for the formation of active sites. The samples calcined in shallow bed possessed lower sulfate content and the S=O stretching vibration was located at lower frequency. Calcination in the presence of water vapor also led to lower catalytic activity, sulfate content, and BET area. Extended calcination reduced gradually the activity and the sulfate content, which underlines the labile property of the active sites. A new interpretation of the function of the calcination step is proposed and compared with models described in the literature.

Redox properties of CeO2 and Pt-Rh/CeO2 were studied by temporal analysis of products (TAP) method using alternative pulses of CO and O-2. A portion of pulsed CO was oxidized to CO2 and a portion of CO was adsorbed on the surface. Pulsing O-18(2) onto the catalyst which has surface species derived from CO, evolved CO2 contained no O-18 suggesting that the surface species will be carbonate ions.

JOURNAL OF POROUS MATERIALS Vol. 13 ( 3-4 ) page： 237 - 244 2006.10

Language：English Publishing type：Research paper (scientific journal) Publisher：SPRINGER

A series of lanthanide (LA) phosphate were prepared by using N-(2-hydroxyethyl) ethylenediane-N,N',Ntriacetic acid (H(3)hedtra) as a chelating agent. The obtained samples were characterized by using X-ray diffraction (XRD), nitrogen adsorption-desorption isotherm, thermal analysis (TG-DTA), transmission electron microscope (TEM) and TPD-ammonia desorption. The results showed that samples prepared through chelating agent route possessed smaller particle size which led to higher specific surface area with increased acidic sites compared with the reference samples prepared free of H(3)hedtra. It was also found that the acidic strength increased gradually from the light lanthanide phosphate to heavy lanthanide phosphate. Besides, pore size of the samples could be controlled by altering the mole ratio of the lanthanide(LA): H(3)hedtra. Pore size distribution of the samples became narrower through synthesis in the presence of H3hedtra. The precursor sol complex was investigated by FTIR and XRD and mesopore formation mechanism had been discussed.
