TITANIUM OXIDE FILM AND ITS FORMING METHOD AND APPARATUS FOR PHOTODEGRADATION TREATMENT

摘要

PROBLEM TO BE SOLVED: To provide a titanium oxide film which contains a low hydrogen overvoltage metal formed by the hydrolysis of a titanium alkoxide or by the burning of the low hydrogen overvoltage metal compound or a titanium sol which contains a silicate or a silica sol. SOLUTION: The above titanium oxide film has a high photocatalytic property. A base substance forming the titanium oxide film is set without a specific jig and with space-saving. An apparatus for photodegradation treatment is simple and compact and capable of exhibiting high photocatalytic property.
