▎ 摘　　要

NOVELTY - Preparing triazinyl-based two-dimensional electrode material, comprises (i) using Schiff base reaction to synthesize nitrogen-rich material with p-phenylenediamine and cyanuric acid, and (ii) using attapulgite to induce synthesized nitrogen-rich material into a two-dimensional structure to obtain a triazine-based aza two-dimensional electrode material. USE - The method is useful for preparing triazinyl-based two-dimensional electrode material. ADVANTAGE - The electrode material: is rich in heteroatoms; has high specific capacitance, and large specific surface area; is a porous structure; facilitates the entry and exit of ions; stabilizes the structure during expansion or contraction; is not easy to collapse; has good stability; and can replace graphene as a good cathode material.
