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.

有序介孔碳是通过无溶剂途径合成的。合成过程包括将间苯二酚，六亚甲基四胺和Pluronic F127的固体原料混合和研磨，然后对复合材料进行热处理。间苯二酚在100°C熔融后似乎形成有序的介观结构。然后，将Pluronic F127在350–400°C的温度下分解，形成直径为6.2 nm的直孔通道。使用KOH通过无溶剂方法将中孔碳活化，从而获得具有1520m ² / g的高表面积的微孔/中孔碳。由于其高介孔率和高表面积，KOH活性炭显示出优异的EDLC特性。
