三维多孔碳纳米膜(CNM),即二氧化硅支撑的CNM(SS-CNM),是通过在介孔二氧化硅(SBA-15)表面形成自组装单层烯二炔化合物,然后进行Bergman环化和碳化而开发的。 SS-CNM 用作电活性材料 Co3O4 的导电载体来制造先进的超级电容器。大部分 Co3O4 簇(占总重量的 66%)浸渍在 SS-CNM 主体中,形成直径为 7 nm 的规则堆积的纳米棒。超级电容器电极材料在水性电解液中的比电容达到1086 F g−1(基于Co3O4为1645 F g−1)。该电极材料的这种非凡的高性能归功于SS-CNM载体独特的孔隙结构,该结构增强了活性材料的使用并缩短了离子和电子的传输路径。
A three dimensional porous carbon nanomembrane (CNM), silica-supported CNM (SS-CNM), is developed by formation of a self-assembled monolayer of an enediyne compound on the surface of mesoporous silica (SBA-15) followed by Bergman cyclization and carbonization. The SS-CNM is applied as a conductive support for the electroactive material Co3O4 to fabricate advanced supercapacitors. A large fraction of Co3O4 clusters (66% of total weight) are impregnated in the SS-CNM host to form regularly packed nanorods with diameters of 7 nm. The specific capacitance of the supercapacitor electrode material reaches 1086 F g−1 (1645 F g−1 based on Co3O4) with aqueous electrolyte. This extraordinary high performance of the electrode material is attributed to the unique pore structure of the SS-CNM support that enhances the use of active material and shortens the transport path of ions and electrons.
