Outlook for improving energy efficiency, conversion rates, and selectivity of plasma-assisted CO 2 conversion

With the escalation of global climate change, reducing carbon emissions and achieving carbon neutrality have gradually become significant concerns. Conversion of CO2 into valuable products is regarded as a viable solution to address these challenges. In comparison to other catalytic approaches, nonthermal plasma (NTP) offers diverse reaction pathways for CO2 conversion under mild process conditions and can ensure selective production of value-added chemicals and fuels when combined with catalytic materials. However, further research is needed to translate plasma-based technologies to the industrial scale. This article focuses on three crucial characteristics of CO2 conversion in NTP: energy efficiency, conversion rate, and selectivity. We overview recent research advances, outline challenges for technological innovations, and propose potential directions for future research.
