Abstract
The morphology, composition and the electrochemical behavior of the anodic nanoporous layer, prepared by the galvanostatic anodisation of titanium, followed by galvanostatic deposition of noble metal particles have been investigated. The morphology and surface characteristics of result electrodes were investigated using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX), respectively. The results indicated that noble metal particles were homogeneously deposited on the surface of TiO 2 nanotubes. The nanotubular TiO 2 layers consist of individual tubes of about 40-80 nm diameters. The electrocatalytic behavior of result electrodes for electro-oxidation of organic compounds (glucose, dopamine, ascorbic acid and hydrazine) was studied by cyclic voltammetry. The results showed that the result electrodes possess catalytic activity toward the oxidation organic compounds.
