Preparation of ultrasmall porous carbon nanospheres by reverse microemulsion-hydrothermal method

摘要

Porous carbon nanospheres (CNSs) have wide applications. A big challenge in materials science is synthesis of discrete ultrasmall porous carbon nanospheres. Herein, we report a facile reverse microemulsion-hydrothermal method to prepare discrete porous CNSs. The obtained CNSs possess an average diameter of 20 nm and pores of 0.7 nm and 3.4 nm. Our work has provided a convenient method for the controllable synthesis of ultrasmall porous CNSs with potential applications.
