Hydrogenation of CO2 to generate valuable chemicals has been widely investigated from the viewpoint of reducing the global warming effect caused by the CO2 emission. It is also of great interest from the aspect of use of carbon source from CO2 for the synthesis of oxygenates and hydrocarbons [1]. In the near future, due to the rapid decline of petroleum reserves, the use of CO2 as C1 building blocks in the organic synthesis would be environmentally and economically attractive. The amount of CO2 to be fixed that way is very small compared to the huge amount of CO2 produced by burning fossil fuels. However, the industrial use of CO2 as a feedstock has so far been limited by its inherent thermodynamic stability. In the past decade, considerable researches have been investigated to develop methods of activating CO2 for subsequent chemical transformation [2]. Processes for synthesis of methanol from syngas catalyzed by Cu/ZnO/Al2O3 have been well established in an industrial process [3]. However, they have been suffered a very poor activity for the hydrogenation of CO2[4].
