    Microscope Analysis of Au–Pd/TiO2 Glycerol Oxidation Catalysts Prepared by Deposition–Precipitation Method

    Gold–palladium bimetallic nanoparticle catalysts prepared by a deposition–precipitation method were effective for aerobic oxidation of glycerol to carboxylic acids. The role of palladium was to suppress C–C bo...

    Preferential Oxidation of CO in H2-Rich Gas at Low Temperatures over Au Nanoparticles Supported on Metal Oxides

    We investigated Au catalysts supported on TiO2, Fe2O3, and ZnO for their preferential oxidation of CO in a H2-rich atmosphere. Both full conversion and selectivity were achieved over Au/Fe2O3 and Au/ZnO around ro...

    Ultramarine colored: Solid-phase elution of Pt into perovskite oxides

    We have found a new route for preparing Pt containing perovskites. Ba containing perovskite powder, (La0.7Sr0.2Ba0.1)ScO3–δ (LSBS), reacted with Pt foil at 1898 K in air, and formed ultramarine colored Pt contain...
