Methods for preparing high crystallinity and surface area porous metal oxides

DWPI Title: Forming metal oxide composite such as titanium oxide, used for e.g. catalysis involves treating water-free solution formed by mixing polymer with hydrophilic/rigid hydrophobic portions to form oxide phase within hydrophilic portion
Abstract: Exemplary embodiments provide materials and methods of forming a metal oxide composite and a porous metal oxide, which can be used for applications including catalysis, sensors, energy storage, solar cells, heavy metal removal and separations, etc. In one embodiment, a one-step solvothermal process can be used to form the metal oxide phase with high crystallinity and high surface area.
Use: For forming metal oxide composite and crystalline metal oxide such as titanium oxide (claimed), used for applications e.g. catalysis, sensors, energy storage, solar cells, heavy metal removal and separations.
Advantage: The formed metal oxide phase of metal oxide composite and the porous metal oxide has high crystallinity and/or high surface area. The method is low-cost, non-destructive, and easy to scale-up.
Novelty: Forming metal oxide composite (M1) involves forming water-free solution by mixing polymer having polymer chain comprising hydrophilic portion and rigid non-hydrophilic portion, organic solvent capable of dehydration reaction, and at least one metal precursor compound; and treating the water-free solution to dehydrate organic solvent such that the metal precursor compound reacts to form metal oxide phase within the hydrophilic portion of polymer, where the rigid non-hydrophilic portion of polymer supports the metal oxide phase.
