THE EFFECT OF ADSORBED LAYERS ON THE ANODIC OXIDATION OF SIMPLE ORGANIC COMPOUNDS. IV. Ag ADSORPTION ON Pt AND ITS EFFECT ON HCOOH OXIDATION.
Abstract
The adsorption of Ag on a smooth Pt electrode in 1M H2SO4 at 40C has been studied from 0.45 to 0.75 V versus RHE in solutions varying from 10 to the -4th to -6th M. The effect of adsorbed Ag on the oxidation rate of HCOOH has been examined at 0.65 and 0.75 V. A diffusion limited adsorption process is indicated. Analysis of the oxidation state of the adsorbed layer suggests, in the one case, a mixed layer composed of Ag singly bonded to a single Pt site with some single bonding to two Pt sites. At the higher coverages, two Ag atoms are apprently attached to a single Pt surface site. The rate of adsorption of Ag(+) is decreased by the presence of HCOOH. (Author)
