轻质烷烃临氧催化活化和选择转化方面的研究进展

Advances in Catalytic Activation and Transformations of Light Alkanes in the Presence of Oxygen

发展非油基碳资源,如煤、天然气、煤层气和生物质等的高效催化转化途径以制备化学品和燃料具有重大的战略意义.在这一背景下,厦门大学催化学科系统地开展了甲烷等轻质烷烃的临氧催化活化和定向转化方向上的基础研究.简要综述了近年来,催化学科部分课题组针对甲烷、乙烷和丙烷选择氧化制甲醛、乙醛和丙烯醛等有机含氧化合物以及丙烷氧化脱氢制丙烯等几个极具挑战性的催化反应,从多相和均相催化的设计和研制、催化剂作用机理和构效关系、活性氧物种的表征、催化反应机理表征和理论模拟等几个方面所开展的基础研究工作的进展.

To develop efficient catalytic routes for the utilization of non-petroleum carbon resources such as coal,natural gas,coal-bed gas and biomass is of high strategic significance.Under this background,in recent years,the Catalysis Division of Xiamen University systematically performed fundamental research on the catalytic activation and selective transformations of light alkanes such as methane in the presence of oxygen.This review briefly summarizes the research advances on selective oxidations of methane,ethane and propane to formaldehyde,acetaldehyde and acrolein as well as the oxidative dehydrogenation of propane to propylene achieved in some research groups.These target reactions are highly challenging and have been approached from various aspects,including designing and preparing heterogeneous and homogeneous catalysts,establishing structure-performance relationships,characterizing active oxygen species and reaction mechanisms,and theoretical modeling.
