锰基氧化物催化降解VOCs的研究进展

Latest Research Progress on Catalytic Degradation of VOCs by Manganese-based Oxides

挥发性有机化合物(VOCs)是空气污染的主要来源之一,因其对环境和人体健康的严重威胁而受到广泛关注。催化氧化已被证明是一种高效的降解VOCs技术。而作为环境友好且低成本的材料,锰基氧化物成为热催化或光/热催化中降解VOCs最具竞争力和前景的候选材料。本文总结了近年来各种锰基氧化物催化剂(单一锰基氧化物、锰基复合氧化物、表面改性的锰基氧化物以及锰基整体催化剂)的研究进展。最后,提出了锰基氧化物催化氧化VOCs存在的问题及对未来研究进行展望。

Volatile organic compounds (VOCs) are one of the main sources of air pollution and have received extensive attention due to their serious threats to the environment and human health.Catalytic oxidation has been verified to be an efficient technology for the degradation of VOCs.As environmentally friendly and low-cost materials,manganese-based oxides have become the most competitive and promising candidates for thermocatalysis or photo/thermal catalysis of VOCs.This article summarizes the recent research progress of various manganese-based oxide catalysts (single manganese-based oxides,manganese-based composite oxides,surface-modified manganese-based oxides,and manganese-based monolithic catalysts).Eventually,the existing problems and prospects of the catalytic oxidation of VOCs by manganese-based oxide catalysts are proposed.
