By Yuen Wu

This thesis makes a speciality of the managed synthesis of Pt–Ni bimetallic nanoparticles and the learn in their catalytic houses. It discusses intimately the nucleation mechanism and the expansion technique of bimetallic structures, that's important for a deeper figuring out of the layout of bimetallic catalysts. the writer provides 4 pioneering reports: (1) syntheses of water-soluble octahedral, truncated octahedral, and cubic Pt–Ni nanocrystals and the research in their structure-activity dating in version hydrogenation reactions; (2) a technique for designing a concave Pt–Ni alloy utilizing controllable chemical etching; (3) defect-dominated form restoration of nanocrystals, that is a brand new synthesis approach for trimetallic catalysts; (4) a cosmopolitan building of Au islands on Pt−Ni, that is a great trimetallic nanoframe catalyst. This thesis conjures up researchers operating in fabrics, catalysis in addition to different interdisciplinary areas.
