【摘要】 负载型Pt催化剂由于具有高活性和良好的稳定性,被广泛应用于挥发性有机化合物(VOCs)的催化完全氧化反应中。系统阐述了载体种类、第二金属组分、催化剂预处理、颗粒尺寸等对催化剂反应活性和稳定性的影响,还概述了Pt催化剂对VOCs完全氧化的催化机理及动力学模型。最后,指出了负载型Pt催化剂今后的发展方向。更多还原

【Abstract】 Being of higher activity and better stability,supported Pt catalysts are widely used in catalytic complete oxidation of volatile organic compounds.In this paper,the effects of major factors such as support type,the second metals,pretreatment of catalysts and the size of catalyst particle on catalytic activity and stability of the samples are predicted systematically.In addition,catalytic mechanism of Pt catalysts for complete oxidation of VOCs and the kinetic models are also discussed.Finally,the further development directions for supported Pt catalysts are pointed out.更多还原
