An investigation is reported on lead dioxide electrodeposition from methanesulfonate electrolytes, that additionally containing Ce3+ ions. It is shown, that ion additive influences on kinetics of PbO2 formation without changing of process mechanism. During the deposition are formed lead dioxide electrodes micromodified by cerium that have different physico-chemical properties vs. traditional PbO2-anodes. Electrocatalytical reactivity of electrodes involved in respect to oxygen evolution was investigated. (C) 2013 Elsevier B.V. All rights reserved.
