Abstract

The invention discloses a carbon material/covalent organic two-dimensional gird composite electrode material as well as a preparation method and application thereof. The carbon material/covalent organic two-dimensional gird composite electrode material has the advantages that a graphitized carbon material is taken as a base template, a covalent organic two-dimensional gird layer grows on the graphitized carbon material base in situ, and the covalent organic two-dimensional gird layer is prepared by carrying out reaction on an aroma polyaldehyde compound and diamino-anthraquinone; a covalent organic two-dimensional gird prepared by taking diamino-anthraquinone as a reaction monomer is compounded with the graphitized carbon material for the first time, and a condition for growing the covalent organic two-dimensional gird on the graphitized carbon material is provided; meanwhile, the preparation method is simple and economic, no high-end delicate instrument is needed, no high energy is needed, and the actual production need can be met; and compared with an electrode prepared by directly adopting covalent organic two-dimensional gird crystal powder, the preparation method disclosed by the invention has the advantage that the utilization rate of an electrochemical active group, namely diamino-anthraquinone, is increased.

Description

technical field [0001] The invention belongs to the field of energy material preparation and electrochemistry, and relates to a carbon material / covalent organic two-dimensional grid composite electrode material and its preparation method and application. Background technique [0002] High specific surface area electrodes can be used as electrochemical sensors, electrocatalysis, and enhanced energy storage components, such as batteries, supercapacitors, and fuel cells. Low relative density, light weight, and high specific surface area are the characteristics of nanoporous materials, which make nanoporous materials play an important role in the fields of electrode materials, catalysis, and hydrogen storage materials. Among numerous nanoporous materials, covalent organic frameworks (COFs) have attracted great interest. This material is composed of lighter elements (H, B, C, N, O) formed by strong covalent bonds between atoms to form a very stable nanoporous material. Three-di...
