| Abstract: | The nanometer thin film alloy electrode (Sb-P b -Pt/GC)was prepared by electrochemical methods.Excellent catalytic effect was o bserved on these film alloy material in the electro-reduction of carbon dioxide (CO 2).The reduction can take place at potentials as high as -0 4 V.The oxid ation of reduced products of CO 2 on Sb-Pb-Pt/GC yielded current peaks at arr owd -0 08,0 2 and 0 3 V,while the oxidation of reduction products on a nm-P t/GC electrode gave rise a current peak near 0 4 V.The in situ FTIR spectroscop ic studies confirmed at a molecule level that the products of CO 2 reduction on Sb-Pb-Pt/GC are mainly organic acid and alcoholic compounds,while on a nm-Pt /GC electrode the production of CO 2 is mainly CO species. |
