| 摘 要： | Electrocatalytic oxidation of small organic molecules has attracted considerable at-tentionin system of fuel celll-4. In this research field, Parsons4 pointed out that the electrodeswhich were prepared from non-noble substrates modified by excellent dispersal noblemetal particles and which still exhibited better catalytic activity should be studied. Ionimplantation is a technique with unique advantage and has been used in manyelectrochemical research fieldss'6. The present study is an at-tempt…

| Abstract: | The glassy carbon substrates were bombarded with 5×1017 ions/cm2 of platinum.The surface composition of implanted electrode and concentration-depth profiles of various elements were measured by AES.The chemical state of Pt in glassy carbon electrode implanted with platinum (Pt/GC) was detected by X-ray Photoelectron Spectroscopy (XPS).The electro-oxidation of HCOOH and HCHO have been investigated on Pt/GC and smooth Pt electrodes.The results show that the platinum implanted into glassy carbon is much more active than the smooth platinum metal for electro-oxidation of HCOOH and HCHO. |
