摘　　要：对氯氟烃(CFCs)催化加氢脱氯生产消耗臭氧层物质(ODS)替代品氢氟烃(HFCs)的反应作了简要概述;在此基础上,结合国内外研究现状,详细介绍了催化剂的活性组分、金属前驱体、催化剂载体以及修饰组分的性质对催化剂性能的影响.此外,介绍了催化剂的主要失活原因,并探讨了其失活机理.最后,对CFCs加氢脱氯生产ODS替代品HFCs催化剂的发展趋势进行了展望.The catalytic hydrodechlorination of chlorofluorocarbons （CFCs） into hydrofluorocarbons （ HFCs ） as ozone-depleting substance （ ODS ） substitutes was briefly reviewed. The effects of active phase, metallic precursor, catalyst support, and promoter on the catalytic properties were discussed in detail. Additionally, the main factors leading to catalyst deactivation were addressed and the mechanisms of catalyst deactivation were inherently introduced. Finally, future research and development expectation in the catalysts used for hydrodechlorination of CFCs into ODS substitutes HFCs were presented.
