摘要: 钨硅酸是乙苯氧化脱氢反应的催化剂。其表面酸仅起促进表面积碳物形成的作用,并不影响催化剂的活性,活性中心是表面积碳物[1]。因此,研究积碳物的结构对弄清反应机理进而改进催化剂十分重要。

关键词: 乙苯氧化脱氢, 钨硅酸, FTIR-PAS, 积碳物

Abstract: FTIR-PAS was used for the structural study of carbonaceous material on the surface of tungstosilicic acid which is a catalyst for the oxidative dehydrogenation of ethylbenzene. It turns out that the carbonaceous material contains conjugated double bonds and carbonyl groups.

Key words: Oxidative dehydrogenation of ethylbenzene, Tungstosilicic acid, Infrared photoaceous spec-trometry, Carbonaceous material
