Abstract

Preparation of boron-doped diamond (BDD) modified with Cu₂O (Cu₂O-BDD) electrodes was conducted to study the electrochemical reduction of CO₂. The electrodes were prepared by electrochemical reduction using a solution containing 1mM Cu(CH₃COO)₂ and 0.1 M CH₃COONa (1:1) at pH 5.7 for 60 s. The electrodeposition of Cu₂O at BDD surface was performed by chronoamperometry technique at -0.4 V (vs Ag/AgCl). SEM-EDS and XPS were utilized to characterize the electrodes. At Cu₂O-BDD electrodes, cyclic voltammetry of dissolved CO₂ in 0.1 M NaCl solution exhibited a reduction peak at around -1.3 V (vs Ag/AgCl), indicated the possibility for application in electrochemical reduction of CO₂.
