Electrochemical Performance of Cupric Oxide Loaded Carbon Nanotubes as Electrode Material for CO2 Reduction

This study is conducted to explore the effective and stable electrode materials for electrochemical reduction of CO2. The different compositions (3 - 8%) CuO-supported CNT samples were prepared by a traditional sol-gel method, characterized TGA, SEM, TEM, FTIR XRD. characterization results confirmed uniform impregnation CuO on defects CNT's, which improved utilization meso microporous distribution in electrocatalyst. high surface area stability CuO- CNTs allowed dual conduction electron intermediate species with current density at minimum energy supplied. Linear sweep voltammetry Chronoamperometry used measure electrode's stability, respectively, 8 % was found most progressive composition reduce CO2 efficiently. Further, liquid products analyzed using gas chromatography, 20 faradic efficiency methane measured.
