Ordered nitrogen doped mesoporous carbon assembled under aqueous acidic conditions and its electrochemical capacitive properties

Controllable synthesis of nitrogen-doped mesoporous carbons for supercapacitor applications

“…6,7 Among various heteroatoms, nitrogen atom can greatly improve the specic capacitance of carbon materials by both improving the surface wettability 8 and inducing redox reactions to incorporate pseudocapacitance. 9 Some nitrogen-containing compounds, such as melamine, 10,11 urea, 12 dicyandiamide, [13][14][15][16] have been used to prepare nitrogendoped mesoporous carbons in the applications of supercapacitor electrodes. Dicyandiamide that is low price with the nitrogen content about 66.7%, possesses higher water solubility and reactivity, and thus is an ideal nitrogen source.…”

Synthesis and characterization of boron-doped ordered mesoporous carbon by evaporation induced self-assembly under HCl conditions

“…40 Hence, HCl is a very effective self-assembly regulator, which is used to help mesoporous carbons obtain order structure in some researches. [41][42][43][44][45] The selfassembly process of BPF and F127 under high HCl concentrations is illustrated in Scheme 2. Therefore, BPF resins, with much less hydromethyl groups than ordinary PF resins can also form order-well mesoporous structure by both coulomb force and hydrogen bonding interaction under hydrogen chloride acid regulator.…”

Sustainable Polyurethane‐Derived Heteroatom‐Doped Electrode Materials for Advanced Supercapacitors

“…Studies show that the heteroatom-induced redox reaction can significantly increase the specific capacitance of ACs. [24][25] This phenomenon can be ascribed to the heteroatom-doped AC's ability to create lattice defects and functional groups, thus optimizing the pore structure and improving the electrical conductivity, surface wettability, and utilization of electrode materials. However, co-doping the heteroatoms (e. g., N and O) can be time-consuming and complicated.…”
