Beschreibung
Zusammenfassung:	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. L'invention concerne un matériau carboné poreux 3D dopé à l'azote, sa méthode de préparation et son utilisation. La méthode de préparation comprend : (1) le prétraitement d'un matériau de biomasse dans une solution de cellulase pour obtenir un matériau de biomasse prétraité, le matériau de biomasse étant du bois d'eucalyptus et/ou du bois de peuplier ; (2) la carbonisation du matériau de biomasse prétraité po
