以桥连聚倍半硅氧烷为原料,通过热解除去碳/二氧化硅复合材料中的纳米二氧化硅相,制备了具有高比表面积的多级多孔碳块体。与传统的热活化方法相比,这种活化方法改善了整料的内部和外部之间的均匀性。
Hierarchically porous carbon monoliths with high specific surface areas have been fabricated by removing nano-sized silica phase from carbon/silica composites pyrolyzed from bridged polysilsesquioxane. This activation method improves the homogeneity between inner and outer parts of the monoliths compared to the conventional thermal activation methods.
