• 摘要：研究了Cu、Zn、Al、Cr等氧化物催化剂在二氧化碳氢化固定反应中的催化活性.研究结果表明,一般含铜的催化剂都具有较高的活性和选择性.红外光谱证实二氧化碳加氢反应过程中有甲酸铜中间产物生成,并利用TPD技术对反应物的吸附过程进行了探讨.

• Abstract：The catalytic activities of Cu, Zn, Al, Cr oxide catalysts for the reaction of fixing carbon dioxide were studied. In general, the catalysts containing copper have higher activity and selectivity than that of others. Formate intermediate over catalyst surface during the reaction process was detected and confirmed by IR spectra. TPD technique was used to explore the adsorb process.
