Currently, various approaches (18,24,25) have been at the forefront of efforts in molding hollow mesoporous carbon structures due to the advantageous combination of mesopores and hollow architectures.
In consequence, a kind of ordered mesoporous carbon nanospheres with a high surface area of 263 m 2 g –1, an open and uniform pore size of 5.3 nm, and a hollow void of ∼80 nm diameter can be synthesized through such a facile solution-processed method.
