Abstract:

Composite α-PbO2 coatings with addition of different solid particles were prepared on A1/conductive coating electrodes in 4M NaOH solution with addition of PbO until saturation by electrochemical anode composite electrodeposition technology, doping with different TiO2 and CeO2 nanoparticles. The optimum formula and operating condition of the composite electrode material were obtained as follows: adding PbO solid to 4M NaOH until saturation, TiO2 15 g/L; CeO2 10g/L, temperature 40°C, current density 0.5A/dm2, electrodeposition time 4h. On this condition, the PbO2-(3.77wt%±0.4%)TiO2-(2.13wt%±0.4%)CeO2 composite coating can be obtained.
