摘要
以Pt-Ni双金属纳米晶催化剂为研究主体,围绕如何构建Pt-Ni合金的高活性表面展开,深入理解双金属体系成核与生长的规律。利用最基本的无机化学的知识结合到纳米合成方法学的研究当中,尝试发展新的双金属甚至多金属的合成策略,构建新型的双金属或多金属纳米结构并赋予其独特的几何和电子结构,以期制备高活性、高选择性和高稳定性的Pt-Ni双金属催化剂,并探索新的催化体系或者新的催化性能,揭示纳米晶催化剂结构与性能之间的关系。
We aim to develop novel bimetallic structure and general synthetic methodology. Furthermore, we try to control the support, loading, coordination of the metal atoms through the traditional chemical methods such as chemical etching, precipitation, coordination reactions. The geometric and electric structures of metal sites such as bond distance, bond angle and so on will be further modulated by our synthetic strategies. At last, we will evaluate the catalytic performance of single atoms catalysts through some important model reactions.
