Study on the Low-temperature Plasma Conversion of CO2 and Decomposition Mechanism
Realizing the cyclical and efficient utilization of CO2 has emerged as a pressing issue in the environmental field.Due to its unique non-thermal equilibrium advantages,the low-temperature plasma(LTP)technology can efficiently break C=O double bonds under atmospheric pressure and normal temperature conditions,thus offering a novel solution for ef-ficient CO2 conversion.However,how to improve the conversion rate and energy efficiency of plasma catalysis still needs in-depth research.This review first summarized the current domestic and international advancements in various types of LTP for CO2 conversion.By analyzing the decomposition mechanisms of CO2 under LTP,this review unveiled the key mechanisms that make it challenging to simultaneously improve conversion rates and energy efficiency under plasma en-vironment.Thereby,this review summarized the synergistic effects between catalysts and plasma,and analyzed the influences of catalyst introduction on conversion rates and energy efficiency.Finally,the future research focusing on LTP catalysis for CO2 conversion was pointed out.
