Electrodeposition of composite PbO2-TiO2 materials from colloidal methanesulfonate electrolytes

The influence of particles of colloidal titanium dioxide on the morphology and structure of lead dioxide electrodeposits has been investigated. The presence of colloidal TiO2 particles (at levels of up to 1 g dm(-3)) in the electrolyte leads to an increase in the rate of lead dioxide formation, and a higher TiO2 content in the deposits. The electrodeposition of lead dioxide from colloidal dispersions containing particles of valve metal oxides is considered via an eleven-stage kinetic scheme.
