摘　　要：随着大气中CO2浓度的增加,温室效应导致的全球变暖问题日益严重。CO2加氢合成甲醇是CO2循环利用的有效途径,在环保、能源等领域具有重要意义,其中高效催化剂的研制是实现该过程工业化的关键。本文从催化剂组成、制备方法及反应机理等方面对CO2加氢催化剂的研究进展进行了评述。分析了催化剂中活性中心的状态,归纳了载体和助剂的作用,比较了制备方法的优劣,并对催化反应机理进行了讨论。针对当前存在的问题,指出反应机理的深入探讨和催化剂制备方法的革新是今后的研究重点和主要方向。With the increase of carbon dioxide （ CO2 ） concentration in the atmosphere, global warming problems are becoming more and more serious in recent years. Methanol synthesis from CO2 hydrogenation is an efficient way for the recycle of CO2. This process is of great significance from the viewpoint of environmental protection and utilization of renewable energy, and the catalyst plays a key role in the catalytic process. The recent progresses made in the field of catalyst for CO2 hydrogenation were presented in terms of the component, the preparation method and the reaction mechanism. The nature of the active site in the catalyst was analyzed and the roles of carrier and promoter were summarized. A comparison and comment including the merit and/or the defect of different preparation methods for catalyst was made. Moreover, the reaction mechanisms were summarized and discussed. Based on the problems currently existing in the studies, the further research work should be focused on the investigation of reaction mechanism and the innovation of catalyst preparation method.
