英文摘要 | The electrooxidation behavior of formic acid on Pt-Ru/GC electrode was investigated by CV, multipotential steps and SERS. It was found that formic acid could dissociate spontaneously on Pt-Ru/GC electrode as it dissociated on rough Pt electrode, produce strong absorption intermediate CO and reactive intermediate -COO-. The results demonstrated that Ru could improve the electrocatalytic activity of formic acid on Pt-Ru/GC electrode. As the ratio of Pt and Ru in desposition solution changed from 10:1 to 11, the oxidation potential of CO shifted negatively about 60 mV(from 0.41 V to 0.35 V). Compared to rough Pt electrode, the oxidation potential of CO on Pt-Ru/GC(1:1) shifted negatively 200 mV. These results indicate that SE S is hopeful to be a comprehensive spectroscopy tool of investigating the electrocatalytic reaction mechanism. |
