Abstract

The invention discloses nitrogen-rich hierarchical pore biomass charcoal and application thereof, and belongs to the technical field of environment-friendly functional carbon materials. The inventionaims to solve the problems of low nitrogen content, underdeveloped pore structure and the like of the existing nitrogen-doped biomass charcoal. The preparation method comprises the following steps: putting biomass and carbon nitride into a carbonate aqueous solution, uniformly stirring and mixing, drying, heating a dried material to 800-900 DEG C in an inert atmosphere, calcining, washing a calcined product, and drying to obtain a finished product. Nitrogen-rich carbon nitride is adopted as a nitrogen doping agent, high-nitrogen-content doping is realized, and an activator carbonate is added,so that the pore structure of the biomass charcoal is effectively improved, and the biomass charcoal has good low-temperature hydrogen sulfide removal performance.

Description

technical field

[0001] The invention belongs to the technical field of environment-friendly functional carbon materials, and in particular relates to a nitrogen-rich multi-level porous biomass carbon and its application. Background technique

[0002] Nitrogen-doped carbon materials have broad application prospects in the fields of adsorption, catalysis, gas separation and storage, energy storage and conversion, etc. Nitrogen atom doping can effectively improve the physicochemical properties of porous carbons. The extra lone pair electrons of the nitrogen atom can endow the delocalized π system in the sp2 hybridized carbon framework with negative charge, thereby enhancing the electron transfer performance and chemical reactivity of the carbon material; at the same time, the charge delocalization caused by nitrogen atom doping will change the O 2 Adsorption on carbon materials, so that O 2 The adsorption mode of molecules changed from point adsorption to side adsorption, whi...
