摘　　要：随着大气中CO_(2)浓度不断增加,温室效应等一系列环境问题也日益严重。通过CO_(2)捕集并进行加氢反应合成具有附加值的化学原料和能源载体是CO_(2)循环利用的有效途径,不仅可以降碳减碳,还可以实现碳循环,在环保、能源等领域具有重要意义。CO_(2)加氢可以生成甲酸、甲醇、甲烷、二甲醚等酸、醇、烃、醚有机化合物,其中甲醇作为CO_(2)加氢的重要产物和重要工业化学品,是当前环保、能源和化工领域研究的焦点。而要将该方法工业化的关键是研发高性能的催化剂,使其高效地将CO_(2)转化为CH_(3)OH。本文在介绍CO_(2)加氢制备CH_(3)OH的反应机理基础上,主要按元素分类综述了Ru、Rh、Pd、Ag、Ir、Pt、Au七种贵金属异相催化剂在CO_(2)加氢制CH_(3)OH反应中的最新研究进展,以及活性金属组分、载体等对催化剂活性、选择性和稳定性的影响。With the continuous increase of atmospheric CO_(2) concentration caused by human activities,a series of environmental issues,including the intensification of the greenhouse effect,have become increasingly severe.Synthesizing value-added chemicals and energy carriers through CO_(2) capture and hydrogenation is an effective way to recycle CO_(2).It can not only reduce the concentration of greenhouse gases in the atmosphere,but also meet part of the energy demand,which is of great significance in the environment and energy fields.CH_(3)OH,as a product of CO_(2) hydrogenation,which has a wide range of application values is an important chemical of environment and energy fields.The key to the industrialization of this method is to develop high-performance catalysts for converting CO_(2) into CH_(3)OH efficiently at a controllable cost.This paper mainly introduces the reaction mechanism of CO_(2) hydrogenation to CH_(3)OH and primarily provides a review of the latest progress on seven noble metal heterogeneous catalysts,including Ru,Rh,Pd,Ag,Ir,Pt,and Au,classified by element.Additionally,it discusses the effects of active metal components,supports and other factors on activity,selectivity and stability of catalysts.
