摘要：
The application of perovskite in catalysts has received extensive attention, due to its stable structure and special physical and chemical properties. In this paper, the research progress in strengthening the activity, anti-toxicity, stability and selectivity of La-based perovskite catalysts with different methods is reviewed. The effects of the structure, surface parameters, active oxygen and low-temperature reducibility of La-based perovskite catalysts on the conversion efficiency of volatile organic compounds were analyzed. The optimization of the perovskite synthesis, and the preparation of supported perovskite and doped perovskite to improve the performance of the La-based perovskite catalyst are also introduced. And the future research directions of the La-based perovskite catalysts are prospected, which are to prepare efficient catalysts by doping non-metal elements and combining multiple methods, to integrate catalytic combustion and photocatalytic oxidation for volatile organic compounds conversion, and to further use experiments and simulations in seeking the ideal catalyst for the catalytic oxidation of volatile organic compound mixtures to meet industrial needs. © 2021, Chemical Industry Press Co., Ltd.
