摘 要:CO_2催化加氢合成甲醇是实现CO_2有效利用的理想途径之一,而高效催化剂是提高反应转化率和选择性的关键所在。概述了CO_2加氢合成甲醇的反应历程和催化作用机理,讨论了催化活性中心Cu粒子的价态、晶面结构和组分对催化性能的影响,总结了ZnO的作用及形貌的影响,归纳了CO_2加氢制甲醇催化剂载体和助剂的作用,比较了各种催化剂制备方法的优缺点。The catalytic hydrogenation of carbon dioxide to methanol is considered as one of the ideal ways to utilize carbon dioxide effectively, and the efficient catalysts are the key for increasing the conversion of carbon dioxide and the selectivity to methanol. In this paper, the catalytic reaction mechanism for the catalytic hydrogenation was summarized. The influences of the valence state, crystal structure and composition of copper-based catalysts on the catalyst performances were discussed, and the effects of ZnO as cocatalyst and support on the performances of the Cu/ZnO catalysts were analyzed. The advantages and disadvantages of the preparation methods were introduced.
