摘要：

Platinum implanted glassy carbon electrode(Pt/GC) was fabricated and implantation dose is 5X10(17) ion/cm(2). The surface elements composition and the concentration-depth profiles of various elements of platinum implanted glassy carbon electrode (Pt/GC) were measured by AES. The chemical state of Pt on Pt/GC electrode was detected by XPS. The electro-oxidation of HCOOH in 0.5 mol/L HClO4 solution and electro-oxidation of HCHO in five kinds of weak basic solutions have been investigated on Pt/GC and smooth Pt electrodes, respectively, The results show that the catalytic activity, according to the real surface area, of Pt/GC electrode is better than that of pure Pt electrode in electro-oxidation of formic acid and formaldehyde, It is possibly related to Pt nanometric clusters formed in bombing, On the same electrode, the currents of oxidation of HCHO in difference weak basic solutions are different, It shows that anion has an obvious effect on the electro-oxidation of HCHO.
