Abstract

The influence of particles of colloidal titanium dioxide on lead dioxide electrodeposition from nitrate electrolytes was studied in the work. Addition of the nanostructured ТiO2 particles to the electrolyte increases the rate of lead dioxide formation. This enhancement is ascribed to extra nucleation sites contributed by Ti–O radicals generated at the TiO2 surface by OH species, in turn formed by discharge of water.A four stages kinetics scheme is proposed for description of the process of lead dioxide electrodeposition in presence of oxides of the valve metal in colloidal solutions. It is suggested that the presence of TiO2 nanoparticles influences crystallization, charge transfer and diffusion stages.
