SYNTHESIS OF ORDERED MESOPOROUS CARBON-SILICON NANOCOMPOSITES

摘要

A method for preparing ordered mesoporous silicon carbide (OMSiC) nanocomposites uses an evaporation-induced self-assembly of a precursor composition that preferably includes a phenolic resin, pre-hydrolyzed tetraethyl orthosilicate, a surfactant, and butanol. The precursor mixture is dried, cross-linked and heated to form ordered mesoporous silicon carbide material having discrete domains of ordered, mesoscale pores.
