Abstract

A new process was developed to form high performance photocatalyst film of titanium dioxide by oxidizing titanium metals in the burning flame of acetylene gases. The oxide film by this process has much superior resistance to scratch, wear and chemical reactions to a conventional titanium dioxide spray coating film. Further, this film shows superior performances in the visible-light photo-catalysis; ten times or more of photo-current density and wide absorption wave range up to 490nm comparing with the conventional spray coating film up to 410nm.
