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.
