Abstract

The invention belongs to the technical field of preparation of porous carbon materials, and discloses a porous carbon material with a high specific surface area by virtue of fungal pretreatment as well as a method and application thereof. The method comprises the following steps: (1) drying and crushing waste biomass to obtain crushed waste biomass; 2) carrying out the constant-temperature oscillation reaction for the crushed waste biomass and fungal spore suspension in a liquid culture medium, filtering, washing, and drying to obtain a carbonization precursor; carrying out the high-temperature carbonization treatment to obtain a primary carbonized substance; and 3) activating the primary carbonized substance and an activator in inert atmosphere to obtain the porous carbon material with ahigh specific surface area. According to the invention, the porous carbon material is prepared by virtue of the regulation of fungal treatment, so that the waste biomass is effectively utilized, the preparation process is simple, the production cost is low, and the method is environment-friendly; and the obtained porous carbon material is high in specific surface area and unique in aperture distribution and capable of obtaining micro-porous, mesoporous or micro-mesoporous carbon materials. The porous carbon material is applied to the field of adsorption.

Description

technical field [0001] The invention belongs to the technical field of porous carbon materials, and in particular relates to a carbon material with a high specific surface area and a method for preparing a specific pore structure (microporous, mesoporous or micro-mesoporous) by fungal pretreatment and its application in the field of adsorption. in the application. Background technique [0002] with O 3 Extreme air pollution such as photochemical smog pollution and haze caused by PM2.5 have seriously affected the quality of the air environment and human health. Volatile organic compounds (VOCs) as O 3 It is one of the key precursors for the formation of PM2.5 and its effective control and reduction is crucial to improving air quality. At present, the adsorption technology using common porous carbon materials as adsorbents has been widely used in the adsorption of VOCs due to its advantages of low cost and wide adaptability. However, such adsorbents have problems such as l...
