Electrode-surface coordination/organometallic chemistry : iodine and carbon monoxide on well-ordered and oxidatively disordered Pd(111)
Department of chemistry, Texas A & M University, College Station, TX 77843, USA.
The preferential chemisorption of iodine and carbon monoxide from alkaline solutions onto ordered and disordered Pd(111) electrode surfaces has been studied. Surface disorder was brought about by repeated electrochemical oxidation-reduction cycles. Experimental techniques employed included voltammetry, low-energy electron diffraction, Auger electron spectroscopy, and temperature programmed desorption. The goals of the study were to: (i) help establish the selective coordination chemistry of Pd(111) electrode surfaces, (ii) determine the influence of long-range interfacial order on such chemistry, and (iii) obtain new insights into the nature of the disorder-to-order surface reconstruction brought about by in situ chemisorption of iodine.
