Abstract: Based on the oxidative carbonylation mechanism of cuprous chloride, copper chloride，and copper zeolite catalysts，new research progress in heterogeneous catalysts, including category, structure，activity center and preparation are summarized. Their catalytic performances are analyzed respectively. The activity and stability of cobalt catalysts are improved by sol-gel technique and encapsulated in zeolite. For palladium and copper catalysts，the methanol conversion is increased and the loss of chlorine is suppressed after the modification of supports and the addition of appropriate promoters. Chlorine-free copper catalysts can avoid equipment corrosion，but there is some decrease in catalytic activity and selectivity of DMC. Finally，by utilizing variety of modern characterization and analysis techniques，the surface process can be studied to understand the mechanism of methanol carbonylation deeply, so that real innovations and breakthroughs can be made in the design and the development of catalysts.
