Study on Photoelectric Catalysis Reduction of CO₂ on a WO₃ Modified Cu₂O Composite Electrode

Abstract:

The electrochemical reduction of carbon dioxide (CO₂) using WO₃ decorated Cu₂O (Cu₂O-WO₃) composite was investigated in KHCO₃ solution saturated with CO₂ by cyclic voltammetry. The electrode which shows a good ability of electrochemical CO₂reduction chosed nickel foam as substrate with Cu₂O and Cu₂O-WO₃deposited on it. WO₃ modification can improve the ability .The results of cyclic voltammetry show that catalytic activity of Cu₂O-WO₃ mixture is affected by effective contact area .
