Carbons with Extremely Large Volume of Uniform Mesopores Synthesized by Carbonization of Phenolic Resin Film Formed on Colloidal Silica Template

摘要

Since the pioneering work by Knox et al.on the use of porous silica spheres as hard templates to prepare uniform carbon beads for chromatographic separations,mesoporous carbons have attracted a lot of attention.Especially,the idea to employ ordered mesoporous silicas(OMSs,such as MCM-41 and SBA-15)as templates,instead of conventional silica particles that have disordered porosity,led to the discovery of ordered mesoporous carbons(OMCs)in 1999,which turned out to be a breakthrough in the area of nanomaterials.
