Thermally induced structural changes in SBA-15 and MSU-H silicas and their implications for synthesis of ordered mesoporous carbons

Abstract

SBA-15 and MSU-H silicas were synthesized and subjected to calcination at temperatures in the range from 823 to 1273 K. The porous structures of the resulting samples were studied using X-ray diffraction and nitrogen adsorption. The pore connectivity was elucidated using the inverse carbon replication procedure. The structures of carbon inverse replicas were studied using XRD and nitrogen adsorption.
