The electrocatalytic oxidation of methane to ethane and ethylene has been carried out using an Li+ ion conductor as a solid electrolyte. The electrochemical cell used was Au I (Li2O)0.17(BaO)0.07(TiO2)o.761 Au, and the experiments were conducted at 850°C with a mixture of 8.3% methane and 1.6% oxygen in argon. By applying an ac voltage of 3 V at a frequency of 10 Hz to the cell, the conversion of methane and the selectivity to C2 hydrocarbons were enhanced 2 and 1.5 times more than at the open circuit, respectively. © 1995, The Electrochemical Society, Inc.

An electrochemical cell, Pd|YSZ|Pd, was constructed in order to remove both NO and CH4 in the presence of excess oxygen. When direct current was supplied to the cell with a flow of a mixture of NO, CH4, O2, H2O and CO2 at 700° C, NO was reduced to nitrogen at the cathode, and CH4 was oxidized to COx at both the anode and cathode. At the cathode, the reduction of NO and the oxidation of CH4 proceeded with the removal of chemisorbed oxygen species from the Pd surface, and at the anode, the oxidation of CH4 was enhanced by forming an active oxygen atom. © 1995 Chapman & Hall.

Detection of hydrocarbons in air and purification of exhaust gas under lean-burn conditions using solid electrolytes 査読有り

A chemical sensor and an electrochemical reactor without the need for the geometry of two electrode compartments have been fabricated using high temperature-type proton and oxide ion conductors, respectively. Pd|CaZr0.9In0.1O3-α Au, responds quickly to dilute hydrocarbons (CH4, C2H6 and C3Hg) in air at 700 °C and changes an electromotive force (EMF) in proportion to the hydrocarbon content. Pd | yttria-stabilized zirconia (YSZ) | Pd, can remove both NO and CH4 in the presence of excess O2 at 700 °C. By passing the direct current through the cell, NO is reduced to N2 at the cathode, and CH4 is oxidized to COx at the anode. The efficiency of removal is independent of the presence of H2O and CO2. © 1995 Springer.

An amperometric sensor to detect D2O in a mixture of H2O and D2O has been studied using CaZr0.9In0.1O3-α as a high temperature protonic conductor. When the sensor heated at 900°C was exposed to air passed through the H2O+D2O mixture at 20°C, it could respond to D2O in the concentration range of 5% to 100% with a 90% response time of about 15 min. The sensing mechanism was based on a H/D isotope effect on resistance of both bulk oxide and electrode reaction. From temperature programmed desorption (TPD) and complex impedance methods, it was found that an increase in bulk resistance was ascribed to a decrease in mobility of the charge carrier. Current interruption method indicated that overpotentials of both anodic and cathodic reactions were increased by replacing protons with deuterons. © 1994.
