Conversion of CO2 in a low-powered atmospheric microwave plasma: in-depth study on the trade-off between CO2 conversion and energy efficiency

Abstract The influence of microwave input power (P) and gas flow rate (F) was compared by analyzing the change of CO2 conversion and energy efficiency with the specific energy input. It was found that the influence of input power and flow rate on CO2 conversion (P > F) is opposite to that on energy efficiency (P
