The climate effects caused by greenhouse gases represented by CO2 are increasingly prominent, and global carbon reduction is urgent. Plasma technology has unique advantages in converting CO2 and it shows good prospects in achieving CO2-resource conversion. This paper reviewed the research results of plasma technology for CO2-resource conversion in recent years, mainly introduced the main process parameters and evaluation indicators of plasma converting CO2, summarized the effects of process parameters, active species and background gases on CO2 conversion, and focused on analyzing the synergistic effect of dielectric barrier dischange (DBD) plasma synergistic catalysis on CO2 conversion. Finally, in view of the problems and challenges faced by plasma synergistic catalysis for CO2-resource conversion, several key research directions in the future were proposed: 1) furtherly reveal the reaction mechanism of plasma converting CO2; 2) systematically explore the synergistic mechanism of plasma and catalyst; 3) from the perspective of practical engineering applications, more attention should be paid on the engineering amplification, safety risks in use, economic benefits of reactors, and so on. |
