Preparation of Platinum Implanted Glassy Carbon Electrode and Electro-oxidation of Formic Acid and Formaldehyde

摘要

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.
