缺陷型金属氧化物脱除气体污染物研究进展
Research progress on gas pollutants removal by defective metal oxides
摘要
Abstract
Metal oxides are widely used in the field of gas purification because of their adjustable structure,easy modification and low cost.However,the reaction activity of metal oxides without defective structures to gaseous pollutants is low,and the selectivity still needs to be improved.After introducing crystal defects into metal oxides,their crystal structure and physicochemical properties can be changed,thereby significantly improving their adsorption activity and selectivity to gases.Nevertheless,in gas removal reactions,the promoting mechanism of defects is extremely complex,which makes it difficult to explore the mechanism of defects in the reaction between metal oxides and gases,and also makes it challenging to apply the research results of reaction mechanism to guide the strategic introduction of defects.In this review,the types of defects in metal oxides are summarized,and then the methods of introducing defects are classified and summarized,and the application status of defect metal oxides in gas purification field in recent years is summarized.Finally,the improvement methods and future research directions of metal oxide defect engineering are prospected,in order to provide reference for the subsequent research on the construction of metal oxide defect engineering and the reaction mechanism of defect promotion.关键词
