This project to tend to develop a mild, non-hydrothermal, non-solvothemal solution synthetic route for the controllable preparation of group VIII bimetallic nanostructures including their solid solutions, and to investigate the growth mechanism of the nanoparticles and their catalytic performances in carbon-carbon cross-coupling reaction with colligative-like property in both oil and water systems. In the current proposal, the composition and structure of the biematallic nanoparticles will be tuned with the variation of reaction conditions, typically via kinetic controlling in the specific procedures, and the reaction and growth mechanisms will be revealed at the same time. In addition, the physical and chemical properties, especially the nanochemistry of catalytic activity of the biemetallic nanoparticles will be evaluated via performing catalysis of carbon-carbon cross-coupling reactions such as the ones of Suzuki, Ullmann and Stille ones. Through the intensive investigations, the highly catalytic performances of the catalysis and the relations between the properties with the composition and structure of the bimetallic nanoparticles, mainly the colligative-like property, will be achieved. This proposal will provide a feasible way to group VIII bimetallic nanoparticles, which is also available for various systems of bimetals, and the pre-proposal study has suggests that the bimetallic nanoparticles have obvious merits for the catalysis of organic reactions since that the bimetallic nanoparticles as catalyst can be easily performed in solutions without any surface modification and addition of phosphorus ligands. This work also presents a new space for the understanding of nanocatalysis and nanochemistry of bimetals, which may provide potential applications in techniques.
