Nanomaterials, Год журнала: 2023, Номер 13(11), С. 1744 - 1744

Опубликована: Май 26, 2023

Porous carbon materials have demonstrated exceptional performance in various energy and environment-related applications. Recently, research on supercapacitors has been steadily increasing, porous emerged as the most significant electrode material for supercapacitors. Nonetheless, high cost potential environmental pollution associated with preparation process of remain issues. This paper presents an overview common methods preparing materials, including carbon-activation method, hard-templating soft-templating sacrificial-templating self-templating method. Additionally, we also review several emerging such copolymer pyrolysis, carbohydrate self-activation, laser scribing. We then categorise carbons based their pore sizes presence or absence heteroatom doping. Finally, provide recent applications electrodes

Abstract Heteroatom‐doped porous carbon materials with distinctive surface properties and capacitive behavior have been accepted as promising candidates for supercapacitor electrodes. Currently, the researches mainly focus on developing facile synthetic method unveiling structure‐activity relationship to further elevate their performance. Here, B, N co‐doped sheet (BN‐PCS) is constructed by one‐pot pyrolysis of agar in KCl/KHCO 3 molten salt system. In this process, urea acts directing agent guide formation 2D morphology, decomposition KHCO boric acid creates rich micro‐ mesopores framework. The specific capacitance optimized BN‐PCS reaches 361.1 F g −1 at a current density 0.5 A an aqueous KOH electrolyte. Impressively, fabricated symmetrical affords maximum energy 43.5 Wh kg power 375.0 W 1.0 mol L TEABF 4 /AN It also achieves excellent long‐term stability retention 91.1% Columbic efficiency 100% over 10 000 cycles. This study indicates effective engineering advanced high‐performance storage devices.
