Abstract

Mesoporous carbons synthesized by the film-type replication of colloidal silica and SBA-15 templates are studied by electron microscopy and nitrogen adsorption. This synthesis strategy involves the formation of thin carbon film on the pore walls of these templates using resorcinol-crotonaldehyde polymer as carbon precursor. For the silica templates consisting of 20-80 nm colloids this synthesis affords carbons with extremely large pore volumes (5-9 cm³/g) and uniform spherical pores reproducing the size of the colloids used.

Funding

This research was supported in part through subcontract under the NIRT DMR-0304508 Grant from NSF awarded to the Carnegie Mellon University. The EM characterization of the carbon samples and SBA-15 silica was conducted at the Center for Nanophase Materials Sciences, which is sponsored at Oak Ridge National Laboratory, by the Division of Scientific User Facilities, US Department of Energy. Precision Colloids as well as Grace Davison are acknowledged for providing free samples of colloidal silicas.
