The properties of anodic passive films potentiostatically formed on polycrystalline gold in aqueous phosphate solutions were studied using voltammetry, electrochemical impedance spectroscopy, and contact angle measurements. The nature of the gold oxi

The electrooxidation of hydrogen on platinum and gold electrodes is comparatively described in this paper. The reaction is faster on platinum than on the gold surface, because the reactive diffuses inside of the gold metal. This process is complicate

The effect of strong cathodisation of platinum electrodes in 0.5 M H 2 SO 4 aqueous solutions is investigated using electrochemical and surface analysis techniques. This pretreatment activates the electrode for methanol electrocatalytic oxidation, wi

The growth of polypyrrol layers on gold electrodes in phosphate solutions of pH = 6.7 was analyzed using “in situ” voltammetric and ellipsometric techniques. Significant variations in optical indices and thickness were detected as a function of t

Electrochemically synthetized poly(o-toluidine) (POT) films were studied in 3.7 M HClO 4 and I M HClO 4 solutions. The optical indices n - i k, at 0.1 V and 0.6 V were calculated in the 405 nm < λ < 580 nm range. Undoped films show an increase in th

The formation of an inhibitive film of benzotriazole (BTAH) on the surface of 304 stainless steel (SS) in 0.01 M H 2 SO 4 , was studied by voltammetric and ellipsometric measurements. BTAH acts as an inhibitor of the corrosion process on the entire r
