摘要
作为一种过渡金属氧化物,锰氧化物以其多晶型、储/释氧能力强、蕴含丰富氧物种、结构缺陷可控等优点被广泛应用于苯系物的热催化氧化.其中,具有众多特性的氧空位能有效促进苯系物的完全催化氧化,因而成为各界研究的焦点.我们综述了常见的氧空位构建方法及表征技术,并总结了在苯系物催化氧化过程中,锰氧化物中氧空位的几种重要作用机制对催化活性和抗水性能的积极影响.最后对氧空位构建新方法、形成机理、具体过程及其在锰氧化物热催化氧化苯系物领域中的应用进行了总结和展望.
With its merits of polymorphism,strong oxygen storage/release capacity,rich oxygen species and controllability of structural defects,manganese oxide,a transition metal oxide,is frequently utilized in the thermal catalytic oxidation of benzene series.Thereinto,oxygen vacancies(OVs)with many characteristics have attracted the attention of researchers from various circles because they can efficiently promote the complete catalytic oxidation of benzene series.We reviewed the common construction methods and characterization techniques of OVs,and summarized the positive effects of several important mechanisms of OVs in manganese oxide on catalytic activity and water resistance in the catalytic oxidation of benzene series.Finally,this research concludes by summarizing and predicting novel techniques,creation mechanisms,particular processes and their applications in the area of benzene series thermocatalytic oxidation by manganese oxide.
