As the core of CO

2

conversion and utilization

catalysts have been attracting much attention. Although the catalysts prepared by conventional methods show good activity

the specific surface area

dispersion

and particle size of the catalysts need to be further optimized. Recent studies have shown that plasma preparation as a new catalyst preparation method has great potential. In this paper

the advantages

disadvantages and applications of conventional preparation methods in CO

2

conversion field in recent years are analyzed from the perspective of catalyst preparation methods. Secondly

the research status of cold plasma preparation is introduced. The catalyst with smaller particle size

higher dispersity and specific surface area can be prepared by the plasma preparat

ion method at low temperatures compared with the conventional preparation method

and the synergistic effect between the catalyst and the plasma can further improve the activity and stability of the catalyst

so as to improve the CO

2

conversion rate. In addition

the application prospect of the catalyst prepared by plasma method is also put forward.
