Abstract: The present invention relates to the technical field of electrocatalytic electrode preparation, and discloses a lead dioxide-carbon nanotube adsorptive electrochemical submicroelectrode, a preparation method, and use thereof. The electrochemical submicroelectrode according to the present invention comprises multiple layers of orderly arranged spherical lead dioxide submicroholes communicating with each other, where the carbon nanotubes are partially or completely inserted (in the form of twigs) in the lead dioxide hole and in the wall of the hole. The combined effect of adsorption and catalysis inside the submicroreactor effectively solves the problems of low catalytic efficiency and diffusion control associated with the conventional flat lead dioxide electrode, thus greatly improving the electrochemical catalytic performance of the electrode.

Abstract: An electrode includes a microporous titanium substrate coated with a catalytic layer, and the catalytic layer includes magnetic SnO2—Sb particles. The magnetic SnO2—Sb particles are attached to the microporous titanium substrate through an external magnetic field. The microporous titanium substrate includes a plurality of membrane pores having a pore size of 5-50 μm that is smaller than a particle size of the magnetic SnO2—Sb particles.
