摘要：

Ordered mesoporous carbons (OMCs) with tunable pore size in the range of 3.6-6.2 nm were prepared using the mixture of phenol, resorcinol and phloroglucinol as carbon precursor and triblock copolymer F127 as template via self-assembly method. The OMCs had ordered 2-D hexagonal mesostructure with high specific surface areas (up to 1100 m(2)/g) and pore volume (up to 0.84 cm(3)/g). Nitrogen sorption results demonstrated that the pore size of OMCs can be tuned by varying the composition of carbon precursors and the mass ratio of carbon precursor-to-F127. Systematic research revealed that increasing amount of resorcinol and phloroglucinol in carbon precursors resulted in carbons with larger pore size but less ordered mesostructure. Compared with resorcinol, phloroglucinol facilitated a larger mesopore, while led to a worse mesostructure. (C) 2014 Elsevier Inc. All rights reserved.
