Abstract

Nanoporous carbon framework was synthesized using phenol and formaldehyde as carbon precursors and triblock copolymer pluronic F127 as soft template via evaporation induced self-assembly. Hexagonal mesoporous carbon with specific surface area of 350 m

-g through optimizing the situation was obtained. The effects of different surfactant-phenol molar ratio and presence of salts on specific surface area, pore size and pore volume for all the prepared samples were studied by means of the Brunauer-Emmett-Teller BET formalism, powder X-ray diffraction technique and FT-IR spectroscopy.
