The design of multimodal porous carbons containing numerous electroactive hetero-atoms is restricted by traditional template-assisted methods, which include fussy synthesis approach with low output for the application. Here, we fabricated the nitrogen-enriched multimodal porous carbons from a self-assembled inclusion complex induced by interaction between urea hydrates as host molecules and cellulose molecules as guest molecules for supercapacitor. The novel carbon could be obtained on a gram-scale due to the simple process and widely available precursor, cellulose, from markets and had a three-dimensionally interconnected structure, as well as multimodal porous characteristics and a large amount of nitrogen. Therefore, the fabricated carbons exhibited a high capacitance, good cycle stability and high degree of reversibility in the repetitive charge/discharge cycling. |
