Patent ID: 8268268

Claim:
A rapid method for preparing titania or precursor thereof with controllable microporous-mesoporous structure comprising following steps: (a) treating alkali metal titanate in a moisture atmosphere, which is produced from at least one of normal water vapor, alcohol organic compound-water vapor, and soluble inorganic salt-water vapor with a relative humidity of 2-100% at a temperature of 20-250° C. for 0.5-72 hours; (b) washing the treated alkali metal titanate with water or an acid solution, and (c) heating the alkali metal titanate obtained from the step (b) in air or an organic solvent to produce titania or a precursor thereof with a pore size of 1-20 nm, a pore volume of 0.05-0.4 cm 3 /g, and a specific surface area of greater than 30 m 2 /g.
