摘要: 二氧化碳加氢合成甲醇反应是二氧化碳利用的重要途径,其中催化剂的研究是技术的关键。本文针对反应采用的铜基催化剂,从铜基催化剂的制备方法、活性组分铜的分散度、铜粒径以及铜与载体间界面作用等方面,分别对其影响催化剂的活性、甲醇的选择性以及稳定性作用进行研究综述。通过分析认为:催化剂的制备方法影响催化剂的铜分散度、铜粒径及铜与载体间的作用,从而影响催化剂催化性能。其中在共沉淀法的基础上进行改进是目前催化剂制备方法的研究趋势,且增加铜分散度、减小铜粒径及增大铜与载体间作用对二氧化碳加氢合成甲醇反应铜基催化剂的催化性能有不同程度的影响。该综述为进一步研制高活性、高甲醇选择性和优异稳定性的新型催化剂提供参考。

Abstract: The methanol synthesis from CO2 hydrogenation is the most promising research direction in the utilization of CO2, in which the research of catalysts is the key point.This review focuses on the copper-based catalysts and summarizes the effect factors including copper dispersion, copper particle diameter and the interaction between metal copper and support on the activity, methanol selectivity and stability of copper-based catalyst.The preparation methods have huge influences on the copper dispersion, copper particle diameter and the interaction between metal copper and support which could then affect the catalytic performance.Developments based on the co-precipitation are the research trend of catalysts preparation in nowadays.Improving copper dispersion, decreasing copper particle diameter and increasing interaction between metal copper and support have different effects on the catalytic performance of this reaction.This review of the researches above provides the references for the development of high activity, high methanol selectivity and good stability new catalysts.
