提高碳氧键加氢铜基催化剂稳定性的研究进展
Progress in improving the stability of Cu-based catalysts for C-O bond hydrogenation
摘要
Abstract
Hydrogenation of carbon-oxygen bonds to produce alcohol is a significant hydrogenation reaction with wide applications,such as the hydrogenation of CO,CO2,esters,carboxylic acids,anhydrides,and furfural.In the reaction process,the catalyst is the key to determine the degree of reaction and the distribution of hydrogenation products.The development of copper-based catalysts with high activity and selectivity to replace precious metals has research value and reference significance for the industrial application.Based the most two serious problems of copper-based catalysts,i.e.facile sintering and agglomeration at high temperatures,the researches of copper-based catalysts in the carbon-oxygen bond hydrogenation reaction are reviewed.The methods to avoid catalyst inactivation and increase catalyst stability are introduced,and the stability enhancement of copper-based catalysts by adding different additives,support effects,and constructing special catalyst structures,are discussed.The factors influencing the catalyst stability such as high oxygen vacancy to promote defect and adsorption sites,and confinement to restrict metal migration and aggregation,are summarized.关键词
