摘　　要：纳米催化介于均相催化与多相催化之间,也称为"半多相催化",目前正受到人们越来越多的关注.最近几年,应用双金属纳米材料进行催化研究取得了很大进展,使用这些催化材料可以增加反应活性和选择性,而且能很好地得以回收.本文综述了双金属纳米材料催化的各种有机反应,如选择性氧化/氢化、偶联和其它反应(脱卤、酰胺化、还原氨化、芳基硼酸与烯酮的1,4-不对称加成和氢解).将双金属纳米材料用于催化合成更加复杂的有机分子值得期待.在双金属纳米有机催化领域,基础理论和实际应用尚有较大的发展空间.未来该领域的发展需要开展多学科的合作,包括合理设计和可控制备相关的双金属纳米材料、深入理解催化机理及发展计算催化.Nanocatalysis,which is also known as semi-heterogeneous catalysis,sits at the boundary between homogeneous catalysis and heterogeneous catalysis and has been the subject of increasing interest during the course of the last few years.Significant progress has recently been made towards the catalytic applications of bimetallic nanomaterials,which show high levels of activity,selectivity and recyclability.This review provides a summary of bimetallic nanomaterial-catalyzed organic trans- formations,including selective oxidation,hydrogenation,and coupling reactions,as well as dechlo- rination, amidation, reductive amination, and hydrogenolysis reactions, and the asymmetric 1,4-addition reactions of arylboronic acids to enones.The complex organic molecules using bimetal- lic nanocatalysis would be anticipated soon.There is significant scope for bimetallic nanocatalysts to be further developed in terms of our general understanding of their fundamental properties and practical applications.Future development may benefit from the rational design and controllable synthesis of bimetallic nanomaterials,as well as a deeper understanding of their reaction mecha- nisms and further progress towards the development of sophisticated computational studies in- volving catalysis,which would require interdisciplinary collaborations.
