摘要

有机废气是重要的空气污染物，基于负载型贵金属催化剂的催化燃烧技术因效率高、无二次污染等特点而被广泛研究和应用。但目前催化燃烧技术仍存在高耗能和高成本等缺点。有机废气多相催化燃烧效率均与催化剂一定尺度范围内的结构密切相关。在有机废气催化氧化反应体系内存在从活性中心到高性能催化剂与过程的多尺度效应。依据不同尺度范围内催化剂的功能，对催化剂进行相应的设计和功能强化，是提高催化剂净化效率的有效方式。总结了近年国内外研究者在有机废气催化燃烧贵金属催化剂不同尺度范围内的设计理念和效果，并对有机废气催化燃烧催化剂的未来发展方向进行展望。

Abstract

Catalytic combustion of heavy air polluting organic waste gases over supported noble metal catalysts has been in extensive study and application

due to high removal efficiency and absence of secondary pollution. However

current technology still suffers from various problems such as high energy consumption and cost. There is a strong correlation between combustion efficiency of organic waste gases and dimensional structures of catalysts so that a multi-scale effect exists from microscopic active sites to catalyst and catalyst bed. A comprehensive consideration of function enhancement and design optimization by catalyst functions at each scale level is an effective way to improve removal efficiency of the supported noble metal catalyst. This review summarizes recent domestic and international design strategy and output with consideration of the multi-scale effect in catalytic organic waste gas combustion system

and provides a prospect for future research direction of organic waste gas combustion catalysts.
