    <jats:title>Abstract</jats:title><jats:p>Enhancing NH<jats:sub>3</jats:sub> as a carbon‐free energy carrier of H<jats:sub>2</jats:sub> and next‐generation fuel is a promising approach for a sustainable society. Chemically storing NH<jats:sub>3</jats:sub> molecules in crystal structures offers better selectivity and reusability than storage in traditional porous materials based on physicochemical adsorption; however, designing materials that can be reversibly stored in structural gaps is still a significant challenge. Herein, the use of NH<jats:sub>4</jats:sub>ZnPO<jats:sub>4</jats:sub>, which is previously used as a fertilizer, is proposed as an NH<jats:sub>3</jats:sub> uptake material through a chemical storage mechanism. The NH<jats:sub>4</jats:sub>ZnPO<jats:sub>4</jats:sub> particles synthesized by a wet mechanochemical method with monoclinic and hexagonal crystal structures can incorporate NH<jats:sub>3</jats:sub> molecules and directly transform them into NH<jats:sub>4</jats:sub>Zn(NH<jats:sub>3</jats:sub>)PO<jats:sub>4</jats:sub> without producing byproducts. The chemical storage mechanism depends on the particle morphology; therefore, the uptake amount per surface area surpasses that of porous materials. NH<jats:sub>4</jats:sub>ZnPO<jats:sub>4</jats:sub> exhibited excellent cycling performance due to its reusability, which is regenerated by releasing NH<jats:sub>3</jats:sub> from NH<jats:sub>4</jats:sub>Zn(NH<jats:sub>3</jats:sub>)PO<jats:sub>4</jats:sub> when heated in air at ≈100 °C. Taking inspiration from previously used and familiar fertilizers further extends this new area of innovative materials that can be used for the reversible storage of low‐molecular‐weight gases.</jats:p>

    <jats:title>Abstract</jats:title><jats:p>2D ferroelectrics provide great promise for future electronics owing to their unique properties at 2D limit. Although simple perovskite oxides (such as BaTiO<jats:sub>3</jats:sub> and PbTiO<jats:sub>3</jats:sub>) are an important target for 2D ferroelectrics, controlled synthesis of 2D nanosheets still remains a challenge. Here, this issue is addressed by using a new chemical protocol; unilamellar Ti<jats:sub>0.87</jats:sub>O<jats:sub>2</jats:sub> nanosheets can serve as templates, guiding the solvothermal synthesis of 2D BaTiO<jats:sub>3</jats:sub> nanosheets with a molecularly thin thickness (&lt; 3 nm). Raman spectroscopy, second‐harmonic generation, and transmission electron microscopy characterizations suggest the formation of tetragonal ferroelectric BaTiO<jats:sub>3</jats:sub> nanosheets. Based on piezoresponse force microscopy, BaTiO<jats:sub>3</jats:sub> nanosheets exhibit a clear ferroelectric response with a high Curie temperature (≈100 °C) even down to 1.8 nm thickness. This study provides new opportunities to investigate perovskite ferroelectrics with the critical thickness.</jats:p>
