Abstract

Ordered mesoporous carbons were synthesized through a solvent-free route. The synthesis process involves mixing and grinding of solid raw materials of resorcinol, hexamethylenetetramine and Pluronic F127, followed by a thermal treatment of the composite. An ordered mesostructure seemed to be formed after melting of resorcinol at 100 °C. And then, Pluronic F127 was decomposed at 350–400 °C to form straight pore channels with a diameter of 6.2 nm. The mesoporous carbons were activated by a solvent-free method using KOH to obtain a microporous/mesoporous carbon with a high surface area of 1520 m2/g. The KOH-activated carbon showed a superior EDLC characteristics due to its high mesoporosity and high surface area.
