异相钙钛矿催化氧化技术在水处理中的研究进展OA

The advancement of heterogeneous advanced oxidation technologies(AOTs)represents a major focus in water treatment research,where the development of green and efficient heterogeneous catalysts is of central importance.In recent years,perovskite composite oxides have emerged as promising materials in materials science and catalysis.Due to their high lattice oxygen transfer rate,good electron mobility,outstanding thermal stability,and strong redox properties,perovskite oxides demonstrate significant research value and promising application prospects in water pollution remediation.This article reviews various perovskite-based AOTs,including their use as heterogeneous catalysts to activate different peroxide systems(e.g.,ozone,hydrogen peroxide,and persulfate),as well as peroxide activation enhanced by external energy such as light,electrochemical field,ultrasound,and microwave.In addition,the application scope,efficiency,and mechanisms governing the generation of reactive species generation and oxidation pathways are discussed in detail.The effects of interfacial engineering and structural modulation strategies on catalytic performance are also comprehensively summarized.Finally,the development prospects and current challenges of perovskite-based AOTs are further highlighted.
