Formatted abstract
As-prepared SBA-15 synthesized with different contents of surfactant was put into a swagelok-like high pressure reactor to yield a carbon/porous silica composite. The surfactant was then in-situ carbonized and deposited inside the channels of the pores of SBA-15 via a reaction under Autogenic Pressure at Elevated Temperatures(RAPET). The surfactant acted as both soft-template for as-SBA-15 and carbon precursor for the carbon/porous silica composite. Mesoporous carbon was obtained after etching the silica using an H2O/ethanol solution of NaOH. Nitrogen adsorption/desorption measurements show that the carbon materials possess a high surface area and a narrow pore size distribution. The advantage of the RAPET process, which can simplify the experiments, has been verified with control experiments by calcining the as-prepared SBA-15 in a porcelain boat under nitrogen atmosphere.
