英文摘要： The microstructure- and morphology- controlled synthesis of bimetallic and multimetallic nanoparticles and their application in catalysis are vital to the development of highly efficient nanocatalysts. In this project, the synthesis of bimetallic and multimetallic nanocatalysts and selectively catalytic hydrogenation of nitroaromatics are investigated. The effect of crystal structure and morphology on the catalytic activty of nanocatalysts was also investigated. First, bimetallic and multi-metallic nanoparticles are prepared by the mono-metallic nanoparticle (such as nanosilver, nanocopper, and nanonickel) with different crystal structure and morphology in order to carry out the microstructure- and morphology-controlled synthesis of multi-metallic nanocatalysts. Second, using selectively catalytic hydrogenation of nitroaromatics to aminoaromatics as the model reaction, the structure-activity relationships between the crystal structures and morphologies of multi-metallic nanocatalysts and their catalytic activities are investigated. The selectively catalytic hydrogenation mechanism of bimetallic and multimetallic nanocatalysts with different crystal structures and morphologies is ascertained. Methodology and theory for the preparation of multi-metallic nano-catalysts are suggested. The present work is beneficial to the theoretical research of nanometal catalysis.
