Title:
MACROSCOPIC ARRAY ELECTRODE AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/245868
Kind Code:
A1
Abstract:
The present invention relates to the technical field of electrocatalysis and electrode design and manufacturing, and in particular, to a macroscopic array electrode and a preparation method therefor and a use thereof. The present invention provides a macroscopic array electrode, comprising a conductive substrate and a wettability regulation and control layer deposited on the surface of the conductive substrate. The conductive substrate comprises a base and a cone array on the surface of the base, and the cone array is composed of cones; an included angle between each cone and a vertical direction of the base is 0-85°; and the wettability regulation and control layer is composed of nanoparticle aggregates. In the present invention, the cone and the vertical direction of the base in the array electrode have a certain angle, and good bubble traction force is provided under the combined action of the Laplace force caused by a shape gradient and a buoyancy component; and the wettability regulation and control layer enables the array electrode to have a gasophobic surface in an adhesive state, and the array electrode provided in the present invention is used for performing a gas evolution reaction, so that according to the electrode, bubbles generated by the gas evolution reaction can be directionally transported.
