NITROGEN-DOPED 3D POROUS CARBON MATERIAL, PREPARATION METHOD THEREFOR AND USE THEREOF

摘要

A nitrogen-doped 3D porous carbon material, a preparation method therefor and use thereof. The preparation method comprises: (1) pre-treating a biomass material in a cellulase solution to obtain a pre-treated biomass material, the biomass material being eucalyptus wood and/or poplar wood; (2) carbonizing the pre-treated biomass material to obtain a porous carbon material; and (3) mixing the porous carbon with a nitrogen-containing compound in water, and performing drying and carbonization to obtain a nitrogen-doped three-dimensional porous carbon material. The temperature of carbonization is 800-1000 °C.
