Preparation and Electrocatalytic Performance of Nanosphere Array PbO2 Electrode on Stainless Steel-Based Grid-Like ZnO Film

The invention discloses a preparation method of a stainless steel-based beta-PbO2-MnO2-CeO2-ZrO2 inert composite anode material, and belongs to the technical field of composite anodes. The method comprises the following steps that mechanical grinding and degreasing are carried out on a mesh stainless steel base material, and then the stainless steel base material is soaked into a nitric acid-hydrochloric acid system for etching and activating for 60-80 seconds to obtain an activated mesh stainless steel base; and the activated mesh stainless steel base is taken as an anode, a copper plate is taken as a cathode, electroplating is carried out for 1-2 hours under the conditions of the temperature being 40-60 DEG C, the current density of the anode being 20-40 mA/cm and the stirring rotating speed being 200-250 r/min, and the anode is washed and dried after taken out to obtain the mesh stainless steel-based beta-PbO2-MnO2-CeO2-ZrO2 inert composite anode material. According to the preparation method, the addition of manganese dioxide, zirconium dioxide and the rare earth oxide CeO2 improves the electrocatalytic activity and the corrosion resistance of the electrode material, moreover, the groove voltage is stable, and the power consumption is effectively reduced; the grain growth of lead dioxide is inhibited in the electroplating process, so that the lead dioxide is better refined, the catalytic activity of the anode is greatly improved, and the and the service life of the anode is greatly prolonged; and grains can be refined, so that a coating is more compact, and the corrosion resistance of the anode material can be effectively improved.
