Fatores que influenciam a formação da fase β-PbO2 em filmes eletrossintetizados galvanostaticamente sobre substrato de tecido de carbono
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.
