Plasma-coupled catalysis in VOCs removal and CO2 conversion: Efficiency enhancement and synergistic mechanism.

For the low concentration and intractable VOCs and CO 2 , plasma-coupled catalysis has superior advantages and development potential to deal with them. However, there are critical issues such as efficiency to be further improved and unclear coupling mechanism to reveal. In this review, various types of catalysts are categorized and evaluated by exploring their enhancement effect in plasma-catalytic system to indicate their synergistic excellence and application limitation. Besides, the detailed research of synergistic mechanism between plasma and catalysis is given more attention, which is rapidly progressing due to the development of in-situ experimental techniques and kinetic analysis approach. In our view, the future direction of plasma catalysis is to reveal the synergistic mechanism more deeply for efficiency improvement with efficient catalysts, and pave the way for practical application.
