Abstract
Described herein are methods of making the visible light photocatalysts without the use of templates that can comprise: (1) mixing a metal precursor, an alcohol, and a solvent to form a self assembled shapes at a temperature between the freezing point of the solvent and the boiling point of the solvent, (2) strengthening the shapes at a temperature of about 35° C. to about 300° C. for about 30 minutes to about 96 hours, and then (3) annealing the shapes at a temperature of between about 450° C. to about 750° C. for between about 4 hours to about 16 hours in a gaseous atmosphere. Also described are photocatalysts created by the described methods.
