摘要

In this study, β-PbO 2 -WC composite coatings were synthesized on a substrate using theelectrodeposition method in an electrolyte containing Pb 2+ and WC particles. The preparation processstudy shows that the β-PbO 2 bath containing WC particles becomes more stable for an ultrasonicdispersion time within 30 minutes. WC particles in the β-PbO 2 bath are positively charged, with anionsbeing adsorbed onto the particles. Compared to the β-PbO 2 composite electrode, the oxygen evolutionoverpotentials for the β-PbO 2 -WC electrode are decreased, which demonstrates an energy-savingeffect. The nucleation behavior study shows that the co-deposition of WC particles into the layer haslittle effect on the crystal growth of β-PbO 2 . The main process during the deposition time of 0~5 minwere the nucleation of the β-PbO 2 grains, the adsorption of WC particles, growth of β-PbO 2 grains, andWC particles coated.
