Abstract:

Catalytic combustion of volatile organic compounds（VOCs）is a highly efficient and low pollution technique. Metallic monolithic catalyst was used for eliminating VOCs because of its low pressure drop，high activity，good mechanical strength and high thermal stability. The recent developments in metallic monolithic catalyst with regard to selection of metallic substrate structure，pretreatment of metallic surface，preparation of coating and catalytic combustion of VOCs are reviewed. More efforts should be devoted not only to the preparation of high performance transition coating，but also to the use of multi-component doped precious metals and non-precious metals，such as transition metal oxide，perovskite oxide or spinel oxide as active components on the monolithic catalysts.
