摘　　要：含氯挥发性有机物(CVOCs)由于其毒性、高稳定性和在环境中的持久性而备受关注,有效脱除CVOCs是环境治理领域面临的重要课题,也成为近年来研究的热点。催化燃烧或氧化法因其能耗和成本低有望成为最有效脱除CVOCs的方法之一。对催化燃烧脱除CVOCs的研究进行了综述,重点总结和评述了催化燃烧脱除CVOCs的催化剂,包括金属氧化物、过渡金属氧化物和钙钛矿复合氧化物等催化剂,简要阐述了催化剂的失活类型和再生方法,并对未来催化燃烧法脱除CVOCs的研究进行了展望。Chlorine-Containing volatile organic compounds （CVOCs） have received much attention due to their distinct toxicity, high stability and persistence in the environment. It is a great challenge to remove effectively CVOCs from waste gas in the environment control. Catalytic combustion or oxidation is a prom- ising method for removing CVOCs because of its low energy requirement, low capital costs and diminished formation of NOx. Here, the recent progress in the removal of CVOCs via catalytic combustion or oxida- tion method was reviewed. The typical catalysts used in catalytic combustion of CVOCs were summarized, such as noble metals, transitional metal oxides and perovskite-type catalysts, their nature and perform- ance are discussed in detail. The deactivation and regeneration of catalysts were introduced and the re- search focus in the future was proposed.
