Abstract:
Realizing the cyclical and efficient utilization of CO
2 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 efficient CO
2 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 CO
2 conversion. By analyzing the decomposition mechanisms of CO
2 under LTP, this review unveiled the key mechanisms that make it challenging to simultaneously improve conversion rates and energy efficiency under plasma environment. 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 CO
2 conversion was pointed out.
