金属氧化物上乙酸乙酯催化燃烧的构效关系
Structure-activity relationship of ethyl acetate catalytic combustion on metal oxides
摘要
Abstract
In order to clarify the structure-activity relationship and reaction mechanism of catalytic combustion of ester volatile pollutants on metal oxides,a simple pyrolysis method was used to prepare a series of metallic oxide catalysts MOx(M=Ce,Co,Al,Mg,V,W).The relationship between their surface properties and the performance of EA catalytic combustion was investigated by different characterization methods.Among these MOx catalysts,CeO2 shows the best activity and product selectivity.The surface hydroxyl groups of CeO2 are conducive to the EA hydrolysis,and its moderate acidity weakens the strong adsorption of intermediate products,such as ethanol.In addition,CeO2 has excellent surface lattice oxygen mobility,which facilitates the rapid oxidative decomposition of gas phase products and surface adsorbed chemicals(such as acetates and ethoxides).关键词
