Outline of Final Research Achievements

Size and composition cotrolled alloy nanoparticles were prepared by polyol reduciton, and colloidal reduction methods. Prepared alloy nanopatciles were immobilized on various metal oxides by a sol-immobilization method. Metal oxide was added to the colloidal solution, which was acidified to pH below pzc (point of zero charge) of metal oxide with 0.1 M hydrochloric acid. The successive impregnation method was also applied for the preparation of supported alloy catalysts.
The relationship between local structure and composition of alloy nanoparticles, and catalysis was investigated. The tested reactions were selective reduction by Ni-Pt alloy catalysts, dehydrogenation of alkanes by Pt-Sn alloy catalysts, selective oxidation and hydrogenolysis of glycerol by Ni-Pt and Pt catalysts, and hydrosilylation by Au-Pd catalysts. These supported alloy catalysts showed higher catalytic performance (activity, selectivity and stability) than those of Ni, Pt, Au and Pd catalysts.
