Facile fabrication of novel highly microporous carbons with superior size-selective adsorption and supercapacitance properties.

A facile approach to fabricate novel highly microporous carbons has been developed by direct carbonization of lowly cross-linked polystyrene. The as-prepared highly microporous carbons demonstrate unusually high micropore rate (97%), high surface area (1108 m(2) g(-1)) and uniform pore size distribution, and thus exhibit excellent size-selective adsorption and electrochemical properties.
