Abstract： |
A process for preparing the photocatalyst of mesoporous TiO2 powder or film by the sol-gel method includes such steps as preparing solution from n-butyl titanate, low-carbon alcohol and diethanolamine, adding polyethyleen glycol to obtain transparent precursor sol, evaporating solvent out, drying, crushing, and calcining to obtain the photocatalyst. It has high photocatalytic efficiency and activity. The mesoporous powder and film prepared by the said process has vertically open porous structure which benefits the photocatalytic reaction and high activity. |
