Abstract
In the present study, a new biomass-derived multilayer graphene-like low dimensional carbon material was prepared through the facile one-step carbonization of glutinous rice without conventional KOH chemical activation at 900â¯Â°C in an argon atmosphere. The formation of disordered microporous and mesoporous on carbon, the high specific surface area of 1,371.50â¯m2â¯gâ1, and the pore volume of 2.351â¯cm3â¯gâ1 were confirmed by N2 adsorption and desorption. As a merit of its favorable structural features, the graphene-like carbon electrode exhibits an enhanced electric double layer capacitance (high specific capacitance of 289.9â¯Fâ¯gâ1 and 174â¯Fâ¯gâ1 at 0.5â¯Aâ¯gâ1 and 10â¯Aâ¯gâ1) and excellent cycling stability of 88% after 20,000 cycles at a current density of 8â¯Aâ¯gâ1. This observed electrochemical performance clearly indicates that activated carbon derived from glutinous rice could be used as a promising electrode material in a supercapacitor for electrochemical energy storage.
