氧化物负载型亚纳米金属催化剂的制备及其在有机催化中的应用

Preparation of oxide supported subnanometer metal catalysts and their application in organocatalysis

近几年来,亚纳米金属催化剂(单原子催化剂和团簇催化剂)由于具有高的催化活性和金属原子利用率,在各个领域里具有重要研究意义,尤其是在有机催化反应中表现出优异的催化性能。氧化物因其具有丰富的缺陷位点、表面酸碱位点和高温稳定性等多种优势,作为负载型亚纳米金属催化剂的载体材料。主要综述了氧化物载体负载型亚纳米金属催化剂的几种合成方法及其在氧化反应、加氢反应及偶联反应等有机催化中的应用。

In recent years,subnanometer metal catalysts(single-atom catalysts and cluster catalysts)have important research significance in various fields due to their high catalytic activity and utilization of metal atoms,especially in organocatalysis reactions.Oxides are widely used as carrier materials for supported subnanometer metal catalysts due to their rich defect sites,surface acid-base sites,and high-temperature stability.In this paper,several synthesis methods of oxide supported subnanometer metal catalysts and their applications in organocatalysis such as oxidation,hydrogenation and coupling reaction reactions are reviewed.
