Comments on the Paper Entitled In Situ Studies of Adsorption of Organic Compounds on Platinum Electrodes, by J. O'M. Bockris and K. T. Jeng
Abstract
The paper (1) describes results of experimental and theoretical studies of adsorption of several organic compounds on polycrystalline platinum by the use of radiotracer, ellipsometry and FT-IR techniques. The present comments concern the papers assumptions, research strategy, and methodology. Specific points that will be made below are: (1) since adsorption reversibility was not documented, the application of isotherms for adsorption characterization was not justified; (2) the difference in the roughness factor did not make for a fair comparison of adsorption measurements by various methods employed; (3) in consequence of the choice of hydrochloric acid as the supporting electrolyte, chloride-adsorbate substitution rather than the postulated water-adsorbate exchange, was predominantly observed; (4) adsorption of water and the value of the pzc of platinum affect the testing of testing of the organic adsorbates in a way different from that implied in the discussed work.
