    Abstract: With the continuous growth of global energy demand and serious environmental pollution issues , the current research is focused on seeking a clean and efficient approach to carbon dioxide utilization. Being an important and widely used chemical raw material, methanol also acts as a new type of clean energy with promising prospects. The conversion of carbon dioxide into methanol by catalytic hydrogenation can both reduce carbon dioxide emission and effectively implement the recycle & utilization of carbon resources, which is of great significance to alleviate the energy shortage and environmental problems. Meanwhile the research & development of high activity, selectivity and stable hydrogenation catalysts play a pivot role in methanol production from carbon dioxide during the process. In this work, the research progress of carbon dioxide hydrogenation to methanol is reviewed, and the relevant reaction mechanism and catalysts are deeply discussed.Moreover, the effects of active sites, carriers and morphologies for various catalysts on the reaction performances are summarized, and the application prospects of carbon dioxide hydrogenation to methanol is also envisaged.
