Abstract

Nanoporous carbon framework was synthesized using phenol and formaldehyde as carbon precursors and triblock copolymer (pluronic F127) as soft templateviaevaporation induced self-assembly. Hexagonal mesoporous carbon with specific surface area of 350 m2/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.

Highlights

Porous carbon materials have attracted great interest due to their high surface area, large pore volume, chemical inertness and electrical conducting properties[1]
Various types of ordered nanoporous carbons have been reported via a multi-step synthetic procedure, in which amphiphilic surfactants or block copolymers are employed as soft templates
Zhao and co-workers prepared a variety of ordered mesoporous carbons, “C-FDU-15 and C-FDU-16” with hexagonal (p6m) and cubic (Im3m) structures using phenol/formaldehyde as the carbon precursor and F127 and P123 block copolymers as the soft templates[12]

Summary

Introduction

Porous carbon materials have attracted great interest due to their high surface area, large pore volume, chemical inertness and electrical conducting properties[1]. Ordered mesoporous carbon materials using soft templates were synthesized in 200411. Zhao and co-workers prepared a variety of ordered mesoporous carbons, “C-FDU-15 and C-FDU-16” with hexagonal (p6m) and cubic (Im3m) structures using phenol/formaldehyde as the carbon precursor and F127 and P123 block copolymers as the soft templates[12]. The interaction between both organic precursors and templates and the organic precursors themselves should be considered in an organic-organic assembly for preparing ordered mesoporous polymers and carbons with diversified structures, especially for the common strategies such as hydrothermal treatment[13,14], or the solvent evaporation induced selfassembly (EISA) method[15,16].
