Excessive consumption of fossil fuels has led to an un-precedented increase of carbon dioxide (CO2) emission and triggered a series of environment issues and energy crisis [1].Converting CO2 into hydrocarbon fuels has been regarded as an effective approach,which can solve the environmental problems and fulfill the high requirements of energy con-sumption [2].Methanol is an important chemical and trans-portation fuel,which also plays a vital role in the synthesis of other important chemicals such as methyl tert-butyl ether and dimethyl ether [3].Hydrogenation of CO2 to methanol,which directly utilizes CO2 as the raw material,has not only environmental benefits but considerable economic ad-vantages.
