The nanometer thin film alloy electrode (Sb-Pb-Pt/GC) was prepared by electrochemical methods. Excellent catalytic effect was observed on these film alloy material in the electro-reduction of carbon dioxide (CO2). The reduction can take place at potentials as high as -0.4 V. The oxidation of reduced products of CO2 on Sb-Pb-Pt/GC yielded current peaks at arrowed -0.08, 0.2 and 0.3 V, while the oxidation of reduction products on a nm-Pt/GC electrode gave rise a current peak near 0.4 V. The in situ FTIR spectroscopic studies confirmed at a molecule level that the products of CO2 reduction on Sb-Pb-Pt/GC are mainly organic acid and alcoholic compounds, while on a nm-Pt/GC electrode the production of CO2 is mainly CO species.
采用电化学方法制备了纳米薄膜合金电极（Sb-Pb-Pt/GC）。在二氧化碳（CO₂）的电还原过程中，观察到这些薄膜合金材料具有优异的催化效果。该还原反应可在高达 -0.4 V 的电位下发生。CO₂还原产物在 Sb-Pb-Pt/GC 上的氧化在箭头所指的 -0.08、0.2 和 0.3 V 处产生电流峰，而还原产物在纳米 Pt/GC 电极上的氧化在接近 0.4 V 处产生一个电流峰。原位傅里叶变换红外光谱研究在分子水平上证实，Sb-Pb-Pt/GC 上 CO₂还原的产物主要是有机酸和醇类化合物，而在纳米 Pt/GC 电极上 CO₂的产物主要是 CO 物种。
