Abstract

Ordered mesoporous carbons (OMCs) with well-developed mesopores were synthesized using evaporation-induced self-assembly (EISA). The triblock copolymer P123/phenol-resin/silica composites were prepared by EISA using tetraethyl orthosilicate as the inorganic source, P123 as the structure directing agent and phenol-resin as the carbon source. OMCs were obtained by the carbonization of the composites, followed by the removal of the silica template with a mass fraction 10% HF aqueous solution. For comparison, another OMC was synthesized by using ordered silica as a hard template and impregnated sucrose as the carbon precursor. The samples were characterized by scanning and transmission electron microscopy and N2 sorption. Results indicated that the OMCs had an ordered hexagonal structure with a narrow distribution of mesopores. The optimized OMC was obtained using a P123/phenol-resin mass ratio of 1:0.25. Compared with the OMCs synthesized by the hard template method, the new OMCs had fewer micro- and macropores.
