<P>PROBLEM TO BE SOLVED: To provide a photocatalytic member which improves in a deodorizing performance. <P>SOLUTION: The photocatalytic member 106 is prepared by carrying a photocatalytic material on a filter substrate. The filter substrate is of a fiber cloth, the photocatalytic material contains a titanium oxide photocatalyst and an adsorbent, and the total amount of the titanium oxide photocatalyst and the adsorbent carried per unit area of the filter substrate is 10-50 mg/cm<SP>2</SP>. As the titanium oxide photocatalyst use is made of, for example, a catalyst which contains an anatase-type titanium dioxide and fluorine and has a fluorine content of 2.5-3.5 wt.% in the titanium oxide photocatalyst and in which 90 wt.% or more of the fluorine is chemically bonded with titanium oxide. <P>COPYRIGHT: (C)2010,JPO&INPIT |
