铜基甲醇和低碳混合醇催化剂的研究与催化历程的研究是催化学科中引人注目的领域。近年来,对催化剂的制备与结构、性能的关系有了进一步的认识。人们在寻求组分间结合较紧密,分布较均匀的母体结构及其制备技术,如Feitknecht化合物和尖晶石结构母体的制备。一致的观点认为,适量碱金属离子在催化剂表面的均匀分布有利于提高生成高级醇的活性和选择性。对催化剂的活性位和反应机理,则提出了很多不同的见解。对反应过程中碱金属和CO_2、H_2O等氧化性气体的作用原理也提出了多种解释。本文评述了在这一领域中上述几个方面研究的最新进展,重点讨论了铜系催化剂本身及对催化机理、活性位等方面的不同认识。
Copper-based methanol and low-carbon mixed alcohol catalyst research and catalytic process of catalysis is the field of compelling science. In recent years, the relationship between the preparation of catalyst and the structure and properties has been further recognized. People are looking for more closely integrated, more evenly distributed matrix structures and their preparation techniques, such as the preparation of Feitknecht compounds and spinel structure precursors. The consensus view is that the uniform distribution of the appropriate amount of alkali metal ions on the surface of the catalyst helps to improve the activity and selectivity of the higher alcohol. Many different opinions have been put forward on the active sites of the catalyst and the reaction mechanism. Various explanations have also been put forward on the action principle of alkali metals and oxidizing gases such as CO 2 and H 2 O during the reaction. This article reviews the recent advances in the above aspects in this area, focusing on the copper catalysts themselves and their different understanding of catalytic mechanisms, active sites and more.
