Outlook for improving energy efficiency, conversion rates, and selectivity of plasma-assisted CO2 conversion

With the escalation of global climate change, reduction of 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 technologies, non-thermal 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 approaches to the industrial scale. This article focuses on three crucial characteristics of CO2 conversion in NTP: energy efficiency, conversion rates, and selectivity. We overview recent research advances, outline challenges for future technological advances, and propose potential directions for future research.
