摘要
The glassy carbon substrates were bombarded with 5 X 10(17) ions/cm(2) 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/CC 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.
