Wheat straws-derived hierarchical porous carbon as electrode material for supercapacitor

Deleted Journal, Год журнала: 2025, Номер 2(1)

Опубликована: Апрель 14, 2025

Abstract Hierarchical porous carbon materials hold great potential in electrochemical energy storage, yet their efficient fabrication still faces numerous challenges. Herein, we successfully prepared hierarchical with high specific surface area, broad pore size distribution, and interconnected structures by direct co-pyrolysis of wheat straw potassium hydroxide, leveraging the natural reticular structure straw. As an electrode material for symmetric supercapacitors, CS-800 exhibited excellent performance, retaining 96.94% its initial capacity after 20,000 cycles at current density 1 A g⁻ achieving nearly 100% Coulombic efficiency. Furthermore, to expand application scope, assembled a zinc-ion capacitor using as cathode, which delivered 173 mAh . The channels significantly enhanced ion transport storage capabilities optimized adsorption desorption processes charge carriers. This study demonstrates that preparation high-value-added from biomass waste holds prospects.

Coal-based needle coke (CNC) is an ideal carbon precursor for capacitive materials due to its layered graphitic structure and high electrical conductivity. However, the pore-rich engineering structural inheriting of CNC-derived during conventional activation process present challenges. Herein, a surface oxygen catalytic pore tailoring strategy developed manipulate porous structures carbon. This synthesis uses air oxidation form oxygen-rich microregions on CNC surface, which can effectively tear graphite protective shell, accelerate bonding KOH with groups, catalyze etching reaction between potassium compounds atoms. Thanks low temperature 600 °C alkali-to-carbon ratio 1:1, obtained (PC) inherits long-range from CNC, specific areas be adjusted 182.6 855.4 m2 g–1 by adjusting temperature, far more than that PC (7.6 g–1) derived direct activation. The optimized shows capacitance 308.3 F at 0.5 A retention 212.2 20 68.8%. assembled supercapacitor delivers energy density 8.12 Wh kg–1 power 50.0 W ultralong cycle stability 99% Coulombic efficiency 100% after 50,000 cycles. study validates feasibility catalysis in soft enhancing capacitance.
