“…The C content gradually increases with the N, P, and O contents decreasing as the carbonization temperature increases, which can be ascribed to the continuous decomposition of heteroatom-containing groups. The C 1s spectrum of ONPC is derived into four peaks of C–C/CC, C–N/C–P, C–O, and CO at 284.6, 285.4, 286.3, and 289.0 eV, respectively (Figure b). , The N 1s spectrum of ONPC-700 shows three types of nitrogen at 398.4, 400.6, and 402.0 eV (Figure c), representing pyridinic-N, pyrrolic-N, and graphitic-N, respectively . The negatively charged pyridinic-N and pyrrolic-N devote themselves to pseudocapacitance through creating defects and active sites, and the graphitic-N plays an important role in improving conductivity. , The N content of ONPC-700 is much higher than that of PC-700 (7.95% vs 4.72%), revealing that the use of MF introduces more N groups doped into the carbon framework.…”

Reasonable porous structure and proper heteroatom doping have great influences on electrode materials for supercapacitors. Herein, O, N, and P codoped hierarchical porous carbon (ONPC) was synthesized through a one-pot carbonization−activation strategy by using chitosan as the carbon precursor, phosphoric acid as the activator, and melamine foam as the skeleton. The use of melamine foam facilitated the formation of an interconnected carbon framework and introduced more nitrogen functional groups. Owing to the hierarchical pore structure, large surface area (1588 m 2 g −1 ), and significant heteroatom contents of O (8.61%), N (7.95%), and P (1.34%) in the carbon matrix, the 700 °C carbonized sample ONPC-700 had a specific capacitance of 230 F g −1 at 0.2 A g −1 . A high energy density of 7.5 Wh kg −1 at 100 W kg −1 was achieved for the supercapacitor fabricated with two identical ONPC-700 electrodes. Furthermore, the capacitance retention of the device was evaluated to be as high as 86.53% after 8000 cycles.

“…This bio-nanocomposite showed a specific capacitance of 331 F g −1 in 6 mol L −1 using a KOH electrolyte at 1 A g −1 , with excellent stability of 90% after 10,000 cycles [175]. Major and noteworthy performance values were reached by preparing chitosan-based supercapacitors, which showed specific energy and power density at maximum recorded values of 10.46 Wh kg −1 and 500.08 W kg −1 , respectively [176]. Similarly, Lin et al have created a chitosan-based hydrogel using an ultrafast hydrogelation technique in which carboxylation of chitosan was carried out at 6, 8 and 10 values, thus producing a supramolecular electrolyte hydrogel with excellent specific capacitance of chitosan, chitosan-6, chitosan-8 and chitosan-10 supercapacitors at 35 F•g −1 , 72.5 F•g −1 , 49.2 F•g −1 and 40.5 F•g −1 , respectively [177].…”

Herein, we report recent developments in order to explore chitin and chitosan derivatives for energy-related applications. This review summarizes an introduction to common polysaccharides such as cellulose, chitin or chitosan, and their connection with carbon nanomaterials (CNMs), such as bio-nanocomposites. Furthermore, we present their structural analysis followed by the fabrication of graphene-based nanocomposites. In addition, we demonstrate the role of these chitin- and chitosan-derived nanocomposites for energetic applications, including biosensors, batteries, fuel cells, supercapacitors and solar cell systems. Finally, current limitations and future application perspectives are entailed as well. This study establishes the impact of chitin- and chitosan-generated nanomaterials for potential, unexplored industrial applications.

Hierarchical nano‐micro carbon spheres porous carbon composites are successfully synthesized derived from Euryale ferox shells by the in‐situ decoration of the porous carbon with carbon spheres from carboxymethyl cellulose under the activation of KOH. Effects of fabrication and activation manner on surface area of porous carbons were investigated. The influence of activation temperature, impregnation ratio and modifier were analyzed. The specific surface area, pore volume and average pore diameter of porous carbon was characterized by N2 adsorption isotherms. Porous carbon produced at 800 °C with an impregnation ratio of 3, 2 hours of carbonization time, 20 hours immersion time has been found 2506 m2 g−1, 1.515 cm3 g−1 and 2.4 nm of the optimum specific surface area, pore volume and average pore diameter, respectively. The result of Fourier‐infrared spectroscopy analysis of the prepared porous carbon confirmed that it has abundant functional groups on the surface. The scanning electron micrographs of the prepared porous carbon indicated that a well‐developed pore structure was formed during the experiment.
