Catalysts and Catalytic Mechanism for Methane Oxidative Couplinq: A Status Report

综述了甲烷氧化偶联制乙烷、乙烯催化剂及催化机理研究概况。重点介绍1989年以来对碱及碱土金属化合物、烯土氧化物、复合氧化物等各类催化剂的研究进展。对目前催化剂上甲烷活化途径、甲基自由基在反应过程中的作用机理、不同氧化物种及表面酸、碱位与催化性能的关系等方面的研究状况及不同观点也作了简介。

This review covers work addressing the current research status of the catalyst and catalytic mechanism for the methane oxidative coupling to produce ethane and ethylene.The main attention focuses on the introduction of research progress on alkali and alkali earth compounds, rare earth oxides and complex oxides as catalysts since 1989. Also it includes a brief introduetion of the recent research and different point of view methane activation pathways, the reaction mechanism of the methyl radical in the process and the relation between the catalytic performance and various oxygen species and surface acid base sites as well.
