Description
Abstract:	This study established a database on molecular adsorption at noble metal electrode surfaces. The approach taken was to investigate the chemisorption and stability of important functional groups at electrode surfaces toward electrochemical hydrogenation and oxidation. Forty four organic and inorganic compounds were studied at Rh, Pd, Ir, Pt and Au using thin-layer electrochemistry and X-ray photoelectron spectroscopy. For the platinum-metal electrodes, it was found that the strength of organic chemisorption decreases as: mercaptans > aromatic N > aromatic ring > alkyne > alkene > R2S > arylcyanides > aliphatic N > alcohols > alkyl cyanides > carboxylic acids > esters. The strength of inorganic anion chemisorption decreases as: iodide > sulfide > cyanide > thiocyanate > chloride > bromide. The strength of chemisorption of a given functional group varies with the electrode material in the order Pt > Pd ~ Rh ~ Ir » Au. The surface electrochemical properties of iodine and substituted thiophenols were studied in greater detail at Rh.
