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.%催化燃烧是对挥发性有机物(VOCs)高效率、低污染的处理技术.以金属为基体制备的整体式催化剂因压降低、催化效率高,机械强度和热稳定好等优点是催化燃烧VOCs的研究热点.本文从金属基体结构选择、表面预处理、涂层制备和催化燃烧VOCs几个方面,对近年来金属基体整体式催化剂的研究进行了述评.由此指出,制备高性能的过渡涂层以及采用多组分掺杂贵金属、过渡金属复合氧化物、钙钛矿型氧化物、尖晶石型氧化物等非贵金属作为整体式催化剂活性组分是以后的研究重点.
