温室效应对我们这个星球的环境和人类社会的生存发展已构成越来越严重的威胁，减少主要温室气体之一的CO2的排放已成为一个紧迫的问题.通过加氢转化，将CO2加工为有价值的燃料或化学品被认为是现时固定大量排放的CO2的较好方法.在诸多CO2加氢的可能产物中，甲醇因其既是非石油基洁净合成燃料，又是重要化工原料，还可作为燃料电池氢燃料的载体，因而成为首选的目标产物. 催化剂的研制开发是实现该过程实用化的关键.较早报道可用于催化CO2加氢制甲醇的催化剂是Cu基（尤其是CuO-ZnO-基和CuO-ZrO2-基）催化剂；负载型Pd催化剂对CO2加氢制甲醇也有相当高的催化活性和选择性，并以ZnO负载的Pd基体系...The greenhouse effect of carbon dioxide has been recognized to be one of the most serious problems in the world and a number of countermeasures have been proposed so far. Catalytic hydrogenation of carbon dioxide to produce various kinds of chemicals and fuels has received much attention. Among the options considered, methanol synthesis by CO2 hydrogenation has been also considered to play a role ...学位：理学博士院系专业：化学化工学院化学系_物理化学(含化学物理)学号：1912005140309
