Abstract:
1. A method for preparing a thermally stable crystalline mesoporous metal oxide comprising the steps of: (a) providing a block copolymer/metal oxide solution, wherein the block copolymer comprises a hydrophobic portion comprising sp or sp2 hybridized carbon atoms in each monomer unit, or (b) casting the solution or the colloidal assembly in air resulting in the formation of a polymer metal oxide hybrid; (c) heating the polymer metal oxide hybrid in an inert atmosphere to a temperature of about 700° C. for at least 2 hours resulting in the formation of a porous crystalline metal oxide-carbon composite; and (d) following the heating step, removing the carbon by heating the composite in air, resulting in the formation of a thermally stable mesoporous metal oxide.
