前言制备方法对催化剂的物化特征及催化性能有着重要影响,尤其是对于结构敏感性反应。已有很多证据说明,CO的氢化反应属于结构敏感性反应。载体的作用从前认为主要是起分散和支载作用,以便增加催化剂的有效表面积,提高机械强度及耐热性,但是近年来的研究结果表明,载体除具有上述功能外,尚能在很大程度上改
Preface The preparation method has an important influence on the physico-chemical properties and catalytic performance of the catalyst, especially for structurally-sensitive reactions. There is a lot of evidence that the hydrogenation reaction of CO belongs to the structure-sensitive reaction. The role of the carrier used to be considered mainly from the dispersion and support role in order to increase the effective surface area of the catalyst to improve the mechanical strength and heat resistance, but in recent years, the results show that the carrier in addition to having the above functions, but also to a large extent On the change
