Template-free fabrication of hierarchical porous carbon based on intra-/inter-sphere crosslinking of monodisperse styrene–divinylbenzene copolymer nanospheres

摘要

A novel type of hierarchical porous carbon has been successfully prepared by constructing intra- and inter-sphere –CO– crosslinking bridges of monodisperse styrene–divinylbenzene copolymer nanospheres. The –C6H4– crosslinking bridges ensure good stability of the nanospheres during swelling and crosslinking, and the –CO– crosslinking bridges play an important role in achieving good nanostructure inheritability during carbonization
