Electrodeposition PbO2-TiO2 and PbO2-ZrO2 and its physicochemical properties

► PbO2-based coatings and novel composites with valve metal oxides as a dispersed phase. ► The colloidal properties of the suspesion electrolytes for PbO2 deposition. ► The additions of ZrO2, TiO2 and surfactant have a pronounced effect on the structure of lead dioxide. ► The composite materials have the form of a PbO2 matrix with sub-micrometer and nanosize crystals.
