英文摘要	In order to promote sustainable development, green and renewable clean energy technologies continueto be developed to meet the growing demand for energy, such as supercapacitor, fuel cells and lithium-ion battery. It is urgent to develop appropriate nanomaterials for these energy technologies to reducethe volume of the device, improve the efficiency of energy conversion and enlarge the energy storagecapacity. Here, chitosan/cellulose carbon cryogel (CCS/CCL) were designed and synthesized. Through theintroduction of zeolite imidazole frameworks (ZIFs) into the chitosan/cellulose cryogels, the obtainedmaterials showed a microstructure of ZIF-7 (a kind of ZIFs) coated chitosan/cellulose fibers (CS/CL). Aftercarbonizing, the as-prepared carbonized ZIF-7@cellulose cryogel (NC@CCL, NC is carbonized ZIF-7) andcarbonized ZIF-7@chitosan cryogel (NC@CCS) exhibited suitable microspore contents of 34.37% and 30%,respectively, and they both showed an internal resistance lower than 2 . Thereby, NC@CCL and NC@CCSexhibited a high specific capacitance of 150.4 F g−1and 173.1 F g−1, respectively, which were much higherthan those of the original materials. This approach offers a facile method for improving the strength andelectronic conductivity of carbon cryogel derived from nature polymers, and also efficiently inhibits theagglomeration of cryogel during carbonization in high temperature, which opens a novel avenue for thedevelopment of carbon cryogel materials for application in energy conversion systems.
