| 摘 要： | 二氧化碳（CO2）加氢制甲醇对于解决CO2排放和能源紧缺问题具有重要意义，催化剂的研究是这项技术的关键。铜基催化剂因高效廉价而被广泛研究，但目前的生产效率离实现工业化仍有距离。本文针对铜基催化剂，首先探讨了活性中心的存在形式，然后从活性组分负载量、载体、助剂、制备方法及条件、预处理条件这5个方面，分别分析其对催化剂的活性、选择性以及稳定性等的影响，以期为CO2高值转化为甲醇的铜基催化剂的制备和筛选提供参考。按照广泛接受的双位点机理可知，CO2转化率与铜表面积密切相关，甲醇选择性与强碱位点含量密切相关。因此，各方面因素通过影响催化剂比表面积、铜表面积、铜分散度、碱性位点、铜与载体的协同作用等物理化学参数，进而影响CO2转化率与甲醇选择性。

| Abstract: | CO2 hydrogenation to methanol is an important technique to solve the problems of CO2 emission and energy shortage and the catalyst is the key. Cu-based catalysts have been extensively studied due to their low cost and good performance, but the current production efficiency is still not high enough for its industrialization. In this paper, the existing forms of the active centers of Cu-based catalysts are discussed firstly. Then, the effects of the loading active component, carrier, promoter, preparation method and conditions, pretreatment conditions on the activity, selectivity and stability of the catalysts are reviewed in order to provide a reference for the preparation and selection of Cu-based catalysts for conversion of CO2 to methanol. According to the double site mechanism, the conversion of CO2 is closely related to the Cu surface area, and the selectivity of methanol is closely related to the strong basic sites. Therefore, the above factors affect the CO2 conversion and methanol selectivity by affecting the specific surface area, Cu surface area, Cu dispersion, basic site of the catalyst, and the interaction between Cu and carriers. |
