Factors governing the formation of THE β-PbO _2 phase electroformed galvanostatically on the carbon cloth substrate

摘要

PbO2 films were electroformed onto carbon cloth substrates (twill woven type) in acid conditions using the nitrate precursor by changing the electrodeposition current density, temperature and pH, in order to optimize the formation of the β-PbO2 phase. The crystal structure and morphology of the PbO2 films were investigated using X-ray diffraction(XRD)and scanning electronic microscopy(SEM)techniques. The optimum conditions obtained for formation of the β-PbO2 were presented and discussed.
