PHOTOCATALYST WITH CATALYTIC ACTIVITY EVEN IN VISIBLE-LIGHT RANGE

摘要

Photocatalyst according to the present invention exhibits high catalytic function in the visible light region, together with a photocatalytic property also by the oxide complex having a heterojunction comprising a p-type oxide semiconductor and the n-type oxide semiconductor having a photocatalytic property in at least one of a visible light region characterized in that the configuration. Visible, as the p-type oxide semiconductor having a photocatalytic property in a wide area _{Ca (Zr 0.95 Y 0.05) O} 3-δ perovskite-type oxide of this, the titanium oxide of the anatase type and the like as n-type oxide semiconductor.
