摘　　要：催化燃烧技术是目前处理挥发性有机物(VOCs)最有效的技术之一。在用于催化燃烧VOCs的催化剂中,贵金属因其优异的催化活性而受到众多关注。从活性组分和载体两方面,对贵金属催化剂催化燃烧VOCs的最新报道进行综述。目前,催化剂活性组分的研究重点在于铂、钯、金等单组分贵金属的改性和双组分贵金属的设计合成;对载体的研究主要涉及酸性、孔结构以及载体与金属的强相互作用。未来还需进一步提高贵金属催化剂的抗中毒性能。The catalytic combustion is currently considered as one of the most effective technologies for removal of volatile organic compounds( VOCs). Among the catalysts used in catalytic combustion of VOCs,noble metal catalysts are widely concerned due to excellent catalytic activity. In this paper,the latest reports of catalytic combustion of VOCs by noble metal catalysts were summarized from active components and supports. The researches of active components of catalysts currently focused on the modification of single-component noble metals such as platinum,palladium and gold,as well as the design and synthesis of double-component noble metals. The studies on carriers mainly involve acidity,pore structure and strong metalsupport interaction. Future work still needs to further improve the anti-poisoning performance of noble metal catalysts.
