摘要: Abstract In this work, we present a facile approach to synthesize porous carbon materials via two-step fabrication process using eulaliopsis binata (EB) as the biomass precursor. The dried EB is directly subjected pyrolysis at moderate temperature (500 °C) followed by KOH activation high (850 °C), giving EB-derived carbons. By optimizing KOH/carbon mass ratio and balance porosity capacitance, resulting shows an extremely specific surface area (2273 m 2 g −1 ) pore volume (1.19 m 3 well excellent capacitive performance with capacitance of 373 F g 0.5 A g . Such low-cost, high-performance, biomass-derived electrode material potentially useful for high-power supercapacitors.
