采用自模板法，通过钠钾合金还原四氯化碳合成了一种高比表面积的介孔碳材料。其优势在于，通过还原生成的盐模板只需用水就可轻易去除。所制备的介孔碳具有高比表面积和窄孔径分布。当用作超级电容器电极时，这种材料表现出高的比电容（259 F g⁻¹）和优异的循环性能（6000次循环后电容保持率>92%）。
A high-surface-area mesoporous carbon material has been synthesized using a self-templating approach via reduction of carbon tetrachloride by sodium potassium alloy. The advantage is the reduction-generated salt templates can be easily removed with just water. The produced mesoporous carbon has a high surface area and a narrow pore size distribution. When used as a supercapacitor electrode, this material exhibits a high specific capacitance (259 F g(-1)) and excellent cycling performance (>92% capacitance retention for 6000 cycles).
