Claim Text:
1. A method of making metal oxides having a preselected morphology comprising the steps of: a. preparing an aqueous suspension comprising water, polymeric nanostructures having multiplicities of surface groups including at least one surface group selected from the group consisting of a hydroxyl surface group and a carboxyl surface group, and a metal oxide precursor, said suspension having a preselected ratio of said polymeric nanostructures to said metal oxide precursor of at least 1:3, said preselected ratio corresponding to a preselected morphology; b. depositing said suspension onto a substrate; c. removing said water to form a film; d. removing said film from said substrate; and e. annealing said film to volatilize said polymeric nanostructures and convert said metal oxide precursor to at least one metal oxide selected from the group consisting of metal oxide nanoparticles having said preselected morphology and a metal oxide nanosheet comprising conjoined nanoparticles having said preselected morphology.
