Hierarchically porous heteroatom-doped carbon derived from flue gases for electrochemical energy storage
This study investigated the synthesis of hierarchically porous heteroatom-doped (B and N)
carbon materials from CO 2 or flue gas by CO 2 conversion using NaBH 4 as a reducing
agent and their applications as supercapacitors. The resultant carbon materials exhibited a
high specific capacitance of 210 F/g at 1 A/g, which is higher than that found in a typical
activated carbon. This is because their hierarchical micro-mesoporous structure causes ions
to diffuse into the carbon pores with low resistance. In particular, the process synthesizing …
