In recent years, carbon recycling, which involves reusing CO₂ as a resource, has garnered significant attention. This study focuses on the in-liquid microwave plasma process, known for its simple apparatus design and high reactivity. Previous studies have demonstrated the conversion of CO₂ into valuable substances such as CO and methanol through reduction processes; however, the low yield remains a challenge. To address this issue, this study explores the use of a Cu/γ-Al₂O₃ catalyst, which has been reported to enhance CO₂ conversion rates in gas-phase plasma, aiming to improve the yield in this method.
