摘　　要：碳酸二甲酯(DMC)是一种用途广泛的绿色化工原料。甲醇直接氧化羰基化法合成DMC具有生产成本低、反应条件温和等优点,是合成DMC最重要的方法之一。综述了甲醇直接氧化羰基化合成DMC催化剂的研究进展,包括含卤素铜基催化剂和无卤素铜基催化剂。重点讨论了活性炭、石墨烯和分子筛作为载体对无卤素铜基催化剂催化性能的影响。分析发现,载体的介孔结构、缺陷位和表面基团能够调控Cu粒子的粒径和价态,并抑制Cu物种的团聚和流失,从而提高催化性能。最后,对甲醇直接氧化羰基化合成DMC催化剂存在的问题及未来发展方向进行了展望。Dimethyl carbonate(DMC)is widely used as green raw material for chemical industry.And direct oxidative carbonylation of methanol for DMC synthesis is one of the most important methods due to its advantages of low cost and mild reaction conditions.Herein,the research progress of catalysts,including halogen-containing and halogen-free copper catalysts,for directive oxidative carbonylation of methanol to DMC was reviewed,with emphasis on the effects of catalyst supports,such as activated carbon,graphene and molecular sieve,on halogen-free catalyst.It was found that the mesoporous structure,defect sites and surface groups in the support could enhance the interaction between copper and the support,and inhibit the agglomeration and loss of copper as well,thus improving its catalytic performance.Finally,the existing problems and future development direction of catalysts for synthesis of DMC were prospected.
