摘要: 挥发性有机化合物(VOCs)的控制与去除一直是环境领域的热点问题,催化氧化法因其低温、高效以及副产物无毒害等特点成为去除VOCs最有前景的技术之一。钙钛矿型氧化物(ABO3)是催化氧化VOCs的高效稳定催化剂。为了提高钙钛矿型催化剂的催化效率,有必要针对性地解剖钙钛矿型氧化物的设计,以满足对不同类型VOCs的去除。系统总结了近年来钙钛矿型氧化物催化氧化VOCs的研究进展。首先介绍了钙钛矿型氧化物在VOCs催化氧化中不同的设计策略,包括形貌调控、A位和B位取代、缺陷工程和负载型钙钛矿催化剂,阐明了钙钛矿型氧化物的催化性能与其材料组成、形貌、表面性质(氧物种、缺陷)和本身性质(氧空位浓度、晶格结构)之间的关系;然后介绍了VOCs催化氧化的反应机制和降解途径,并展望了钙钛矿型氧化物催化剂的合理设计和反应机制研究的前景和挑战。

Abstract: The control and removal of volatile organic compounds (VOCs) have always been critical issues in the environmental field. Catalytic oxidation has emerged as one of the most promising technologies for VOCs removal due to its low operational temperature, high efficiency, and non-toxic by-products. Perovskite oxides (ABO3) are recognized as efficient and stable catalysts for the catalytic oxidation of VOCs. To enhance the catalytic efficiency of perovskite-based catalysts, it is necessary to systematically analyze and optimize the design of perovskite oxides to meet the specific requirements for the removal of different VOCs. This paper comprehensively reviews recent advances in the catalytic oxidation of VOCs using perovskite oxides. Firstly, various design strategies for perovskite oxides in VOCs catalytic oxidation, including morphology control, A-site and B-site substitution, defect engineering, and supported perovskite catalysts are introduced, giving a close link between the catalytic performance of perovskite oxides and their material composition, morphology, surface properties (oxygen species, defects), and intrinsic properties (oxygen vacancy concentration, lattice structure). The reaction mechanisms and degradation pathways involved in the catalytic oxidation of VOCs are discussed, and the prospects and challenges in the rational design of perovskite oxide catalysts and the exploration of reaction mechanisms are outlined.
