Effect of the porosity and hydrothermal stability of SBA-16 type mesoporous silica on the characteristics of their carbon replicas

摘要

The use of hard templates is one of the best ways for obtaining ordered mesoporous carbons(OMC)with well controlled morphology and porosity,characteristics that are very important for their use in many technological applications.Since the SBA-16 type mesoporous silica has a 3D connected mesostructure and can be synthesized with different morphologies,we select this material as a hard template and study the influence of its pore(cavities and entrances)size and hydrothermal stability on the qualities of the OMC replicas obtained by liquid impregnation of sucrose.
