Abstract

Abstract The presence of basic centers in some oxides has been recognized for a long time as being important in catalysis [1-4]. Usually both basic and acid sites exist simultaneously. The two centers may work independently or in a concerted way. For instance, in alcohol transformation, dehydration is favored on acidic sites and dehydrogenation on basic centers [3,5]. A large variety of materials are cited as having basic character. They include single-metal oxides (MgO, CaO, ZnO), supported alkali metals (Na/MgO, K/K2CO3), mixed-metal oxides (MgO-A12O3, ZnO-SiO2, MgO-TiO2), zeolites (X and Y saturated with alkaline cations of low electronegativity), hydrotalcite-type anionic clays, asbestoslike materials, carbon-supported basic catalysts, and basic organic resins. ∗ Present address: 16 rue Francois Gillet, 69003 Lyon, France.

碱性沸石:表征及其在吸附和催化中的应用

一些氧化物中碱性中心的存在长期以来被认为是催化反应的重要组成部分[1-4]。通常碱性和酸性位点同时存在。这两个中心可以独立工作，也可以协同工作。例如，在醇转化过程中，有利于酸性位点的脱水和碱性中心的脱氢[3,5]。各种各样的材料被引用为具有基本性质。它们包括单金属氧化物(MgO, CaO, ZnO)，负载碱金属(Na/MgO, K/K2CO3)，混合金属氧化物(MgO- a12o3, ZnO- sio2, MgO- tio2)，沸石(X和Y被低电负性碱性阳离子饱和)，水滑石型阴离子粘土，石棉样材料，碳负载碱性催化剂和碱性有机树脂。*目前地址:法国里昂弗朗索瓦吉列街16号，69003。
