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

Abstract

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, 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 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.
