Abstract: PURPOSE: A method for preparing a thin film or powder of mesoporous transition metal oxide is provided by using a transition metal oxide sol with uniform nanoparticles. Also, a thin film and powder prepared by the method are provided. CONSTITUTION: The method for preparing a thin film or powder of mesoporous transition metal oxide includes (a) adding a structure-inducer such as surfactants or organic polymer to a transition metal oxide sol of the uniform nanoparticles under stirring; (b) coating the resultant mixture on a substrate to form a thin film, or evaporating a solvent under reduced pressure to form a gel; (c) aging the thin film or gel at the constant temperature and relative humidity, for example at a substantially uniform temperature of 0 to 30 deg.C and at a substantially uniform relative humidity of 30 to 80 % to form meso-structure thin film or powders having hexagonal or cubic structure; and (d) optionally, eliminating the structure-inducer such as surfactants or organic polymer from the obtained meso-structure thin film or powder by sintering or ultraviolet-irradiating.
