Abstract:
Provided are a photocatalytic material that improves a decomposition performance and a decomposition rate, as well as a photocatalytic member and a purification device in which the photocatalytic material is used. The photocatalytic member is a photocatalytic member (1) that includes a substrate (10) and a photocatalyst layer (11) formed on a surface of the substrate (10), wherein the photocatalyst layer (11) contains a titanium oxide photocatalyst and zeolite, the titanium oxide photocatalyst containing at least an anatase-type titanium oxide and fluorine, in which a content of the fluorine in the titanium oxide photocatalyst is 2.5 wt % to 3.5 wt %, and 90 wt % or more of the fluorine is chemically bonded to the anatase-type titanium oxide.
