英文摘要：

Researches about carbon dioxide utilization technologies will have great significances for the emission reduction of carbon dioxide from power plants. Based on the theory about catalytic hydrogenation, the mechanisms of the catalysts such as transition metals, namely copper, nickel and zinc, and noble metals including ruthenium, iridium and palladium for carbon dioxide conversion were reviewed. Current researches about the catalytic hydrogenation of CO2mainly focus on the studying and development of highly active catalysts, the analysis and conjecture of reaction mechanism, the improvement of productivity and selectivity, and the optimization of reaction system structure and condition, etc.. The highly active catalysts, for example thermometal alloy, and the transition metal catalyst system will be one of the primary issues in the field of CO2hydrogenation in the future. The reaction mechanism which is complicated with diverse catalysts in carbon dioxide conversion, is worth being researched deeply. As the development of new technics with the characteristics of economy, green and energy saving and the deep researches, it may be possible for the emission reduction and resource industry utilization of CO2from power plants.
