Abstract: PURPOSE: Provided is a method for making a titania nano-particle supported membrane, which is performed with ease and produces the titania nano-particle supported membrane having a high uniformity at a low cost. CONSTITUTION: The method for making a titania nano-particle supported membrane comprises the steps of: reacting glass (substrate) with piranha solution to substitute the silane bonds on the glass surface with hydroxyl groups; reacting the hydroxyl groups with silane compounds to bond the silane compounds to the hydroxyl groups on the glass surface; and reacting with a titania sol solution under an ultrasonic wave irradiation to deposit titania particles to the surface. More particularly, the titania sol solution is obtained by the reaction of HCl/ethanol solution with titanium tetrapropoxide/ethanol solution under ultrasonic wave irradiation.
