While the rapid development of society has brought people a prosperous life, it also brings people a series of negative impacts such as the greenhouse effect and environmental degradation. As one of the eight key tasks, "carbon neutralization and carbon peaking" is constantly being mentioned, which puts forward higher requirements for environmental protection. Therefore, the control of CO2 emissions, its recovery, fixation, utilization and recycle, as well as the reduction of the concentration of CO2 in the atmosphere, has become the issues of great concern for all countries in the world. However, the CO2 molecule is very stable, and its decomposition and activation usually requires the input of high temperature, catalyst and energy such as light and electricity, and high temperature can easily lead to the deactivation of the catalyst. Current CO2 conversion technologies, such as catalytic conversion and biochemical processes, have disadvantages of catalyst deactivation and high energy input. Compared with the above technologies, plasma technology has the advantages of simple operating conditions, easy upgrading, and low energy cost. Using plasma technology, CO2 can be converted into fuels and chemicals with high added value at room temperature and atmospheric pressure. When the plasma technology is combined with the catalyst, the CO2 conversion rate is further improved. Among many CO2 utilization technologies, the hydrogenation of CO2 is conducive to the generation of high-energy-efficiency value-added products, which has practical significance and broad prospects. By investigating and reviewing the influence of catalyst type, reactor structure and operating conditions in the process of plasma catalytic CO2 hydrogenation to methanol, it can provide a better reference for CO2 resource utilization. Studies have shown that when plasma is combined with catalysts, it is more conducive to methanol synthesis, so more attention should be paid to catalysts with higher activity, lower cost, and simpler preparation methods in the future. At the same time, the structure of the reactor will also affect the CO2 conversion rate. Further innovation of the reactor can be considered. At present, the low-temperature plasma reactor with a cooler catalyst bed is more suitable for CO2 hydrogenation to methanol. However, the low-temperature plasma catalytic CO2 hydrogenation to methanol reaction process is relatively complex, and the exploration of the CO2 conversion mechanism requires more modeling.
