Title:
LEAD DIOXIDE-CARBON NANOTUBE ADSORPTIVE SUBMICRON ELECTROCHEMICAL REACTOR AS WELL AS PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/196518
Kind Code:
A1
Abstract:
The present invention relates to the technical field of electro-catalytic electrode preparation and provides a lead dioxide-carbon nanotube adsorptive submicron electrochemical reactor as well as a preparation method therefor and an application thereof. The submicron electrochemical reactor according to the present invention consists of a plurality of layers of submicron lead dioxide spherical pore cavities which are arranged in order, the pore cavities are in communication with one another, and carbon nanotubes are partially or completely embedded (branched) in the lead dioxide pore cavities and on the pore walls of the lead dioxide pore cavities. The submicron lead dioxide pore cavities greatly increase the electrochemical active area of the electrode, and the narrow pore cavity size increases the local concentration of hydroxyl free radicals in the pore cavities. The introduction of the carbon nanotubes provides a large number of adsorption sites for the electrode. The active adsorption effect of the surface of the electrode on pollutants in a body solution is remarkably enhanced. The problems of low catalytic efficiency, diffusion control and the like of a traditional flat plate lead dioxide electrode are effectively solved by means of the adsorption-catalysis synergistic effect in the submicron reactor, thereby greatly improving the electrochemical catalytic performance of the electrode.
