采用浸渍法制备了一系列Cu改性沸石(ZSM-5、MOR、MCM-22、Hβ和SAPO-34),并对其对正丁胺选择性催化氧化性能进行了评价。使用各种分析技术对催化剂的结构、表面酸度分布、氧化还原性质和铜物种进行了表征。结果表明,所用沸石的类型对Cu物种的存在形式和分散性有显着影响,从而影响催化剂的氧化还原性能。在所有考虑的催化剂中,Cu-ZSM-5表现出最好的催化性能。 Cu-ZSM-5的氧化活性和N2选择性与Cu和孤立Cu2+物种的高度分散密切相关,其较弱的酸性有利于正丁胺的吸附和氧化。
A series of Cu-modified zeolites (ZSM-5, MOR, MCM-22, Hβ, and SAPO-34) were prepared by the impregnation method and evaluated forn-butylamine selective catalytic oxidation. The structures, surface acidity distributions, redox properties, and Cu species of the catalysts were characterized using a variety of analytical techniques. The results indicate that the type of zeolite used has a significant impact on the existing forms and dispersion of Cu species, affecting the redox properties of the catalysts. Among all considered catalysts, Cu-ZSM-5 exhibited the best catalytic performance. The oxidation activity and N2selectivity of Cu-ZSM-5 are closely related to the high dispersion of Cu and isolated Cu2+species and its weaker acidity is a benefit to the adsorption and oxidation ofn-butylamine.
