摘要

PROBLEM TO BE SOLVED: To provide a titanium oxide thin film which is deposited on an electrically conductive substrate including a metal and is neither exfoliated nor cracked but has high reliability and to provide a titanium oxide thin film-containing photocatalytic material having suitable coarseness as a photocatalyst, a method for manufacturing the titanium oxide thin film-containing photocatalytic material and an apparatus and a method for cleaning water by using the photocatalytic material.;SOLUTION: The titanium oxide thin film having suitable coarseness as the photocatalyst is deposited on the surface of a coating film by using a titanium oxide-IPA suspension which is irradiated with ultraviolet rays under a predetermined condition and subjecting the electrically conductive substrate including the metal to electrophoretic electrodeposition so that the titanium oxide thin film is deposited and the gas to be derived from IPA is generated at the same time in a cathode electrode.;COPYRIGHT: (C)2007,JPO&INPIT
