Study of Reduction Process of CO-2 on Sb Pb Pt/GC Electrode

The reduction process of CO-2 on Sb Pb Pt/GC electrode prepared by electrochemical co deposition method was studied with cyclic voltammetry and in situ FTIR spectroscopy.The results demonstrated that the prepared Sb Pb Pt/GC exhibited high activity for CO-2 reduction. The onset potential of CO-2 reduction was measured at -0 43 V and the main products of reduction were acid species as determined with in situ FTIR.
