THE EFFECT OF ADSORBED LAYERS ON THE ANODIC OXIDATION OF SIMPLE ORGANIC COMPOUNDS. II. ROLE OF ABSORBED 'HCOOH' SPECIES.
Abstract
The anodic oxidation of 0.1M HCOOH on smooth Pt electrodes in 1M H2SO4 at 40C has been examined. An adsorbed material with a high coverage accumulates on the electrode over a wide potential range. The rate of adsorption of this material is not limited by mass transport. A maximum coverage is indicated at +0.30 V, and this falls to zero by 0.65 V (RHE). This material poisons the main HCOOH yields CO2 reaction at all potentials. The main oxidation process at < or = 0.45 V (RHE) proceeds via an adsorbed intermediate which has not been isolated on the surface. Electron transfer is the rate-limiting step. A possible electroactive solution species is suggested. (Author)
