Abstract

Solid products immobilized from colloids containing intermediates of the reduction of tetrachloroaurate-ions by sodium sulfide on the surface of highly oriented pyrolytic graphite were studied using scanning probe microscopy, cyclic voltammetry and X-ray photoelectron spectroscopy. An evaluation of surface topography and chemical state of both gold and sulfur taking place during colloid’s pre-aging and under electrochemical oxidation in 0.001 M HCl solution were shown
