Mesoporous carbon monoliths (MCM) were prepared by using soluble salt as templates. During the synthesis, a freeze-drying process enables a surface coating of self-assembled Na₂SiO₃ salt particles with sucrose, which is further transformed into carbon by heat treatment. After removal of the salt templates by washing, MCM were obtained. MCM samples exhibit high specific surface area together with high mesoporous volume, whose pore sizes can be tuned from 10 to 30 nm by adjusting the ratio between salt and carbon sources. MCM materials were further used as electrodes in combination with ionogel electrolyte to assemble a solid-state supercapacitor. In this configuration, MCM electrodes show capacitance as high as 75 F g⁻¹ and good rate performance thanks to the carbon monolith pore size selected.

以可溶性盐为模板制备了介孔碳单块（MCM）。在合成过程中，通过冷冻干燥工艺，可以用蔗糖对自组装的Na ₂ SiO ₃盐颗粒进行表面涂层，然后通过热处理将其进一步转化为碳。通过洗涤除去盐模板后，获得MCM。MCM样品具有高的比表面积和高的中孔体积，可通过调节盐和碳源之间的比例将其孔径调整为10至30 nm。MCM材料还与离子凝胶电解质结合用作电极，以组装固态超级电容器。在这种配置下，MCM电极的电容高达75 F g ^-1 由于选择了碳块整体孔径，因此具有良好的速率性能。
