摘　　要：近年来由于纳米技术的发展 ,载体负载的金纳米粒子作为某些化学反应的催化剂有很好的活性 ,由此开辟了金作为催化剂的应用新领域。文中综述了近年来用金作为非均相和均相催化剂在一氧化碳变换反应、加氢反应、各种选择性氧化反应、偶合反应等方面的研究进展。With development of nanoparticle technology in recent years, the gold nanoparticles attached to the carriers have been found to be very active catalysts to some reactions, thus new application of Au as catalysts has been gradually developed. This paper summarizes the latest development of Au working as heterogeneous and homogeneous catalysts in the reactions of CO shifting, hydrogenation and oxidation and coupling etc.. Obviously, Au has a great potential as catalysts in the field of chemical industry.
