摘要：
High value-added products such as aromatic methanol, formaldehyde and formic acid that are derived from methyl aromatic hydrocarbons have been always in short supply worldwide. Because of its high conversion rate, low cost, good safety and other advantages, liquid phase selective catalytic oxidation is the main production method of methyl aromatic hydrocarbon derivatives in industry at present, and the high performance catalyst is one of the key factors. Based on the summary of the catalytic oxidation mechanism of methyl aromatic hydrocarbons, the applications of metal salt catalysts, metal complex catalysts, metal-organic framework (MOF) catalysts, metal oxide catalysts and other catalysts are reviewed in this paper. In order to improve the activity and stability of catalysts and reduce the preparation cost, researchers improves different kinds of catalysts, and find that the improvement of the performance of metal salt and metal complex catalysts lies in the development of corresponding support, while that of the MOFs catalyst should develop high activity Co and Mn metal MOFs catalysts. Besides, the development of metal oxide catalyst should optimize the existing preparation process. Finally, the improvement measures and future development directions of catalysts for liquid phase catalytic oxidation of methyl aromatic hydrocarbon are proposed. © 2023 Chemical Industry Press.
