Carbon-based porous material suitable for electrochemical carbon dioxide capture and preparation method and application thereof

Abstract

The present disclosure provides a carbon-based porous material suitable for electrochemical carbon dioxide capture, a preparation method and application thereof, and belongs to the technical field of electrochemistry. The preparation method comprises: placing urea powder in a high-temperature tube furnace, and introducing nitrogen for 0.5-1.5 hours; pyrolyzing the urea powder under an argon atmosphere and at a preset temperature for 0.5-1.5 hours, and then obtaining a nitrogen-doped carbon-based porous material after cooling and grinding. The present disclosure adopts an in-situ synthesis method, uses urea as a nitrogen source and a carbon source precursor at the same time during the preparation process, and is treated at high temperature in an inert environment, thereby realizing one-step synthesis of a nitrogen-doped carbon material. The material has a large specific surface area and strong adsorption capacity, can effectively adsorb carbon dioxide gas molecules to the surface, and effectively improves the performance and use range of the carbon material in catalysis, adsorption, electrochemistry and the like.
