CO2 hydrogenation using H2 produced with renewable energy sources is a promising research direction to produce methanol, hydrocarbons, synthetic natural gas (methane) and chemicals. In this presentation, I will introduce our group research work on the conversion of CO2 in the recent 10 years. It included the following parts: (1) The conversion of CO2 into methane over Co/ZrO2, it was found that Co/ZrO2 catalyst exhibited high activity and stability through adjusting the metal-support interaction and the special metal-support interface, such as Co-Zr interface. (2) The conversion of CO2 into olefins over Fe-based catalysts, the effect of Fe5C2 was investigated in detail. It was found that Fe5C2 played a key role in the CO2 conversion, different from the role in the CO conversion. (3) The conversion of CO2 into aromatics, it was found that CO2 can be converted into aromatics over ZnZrO2 system, the main products are BTX and trimetylbenzene. （4）The reaction mechanism was investigated by in situ XRD and FT-IR.
