| Research Abstract |
{111} exposed crystal faces of shape-controlled rutile titanium(IV) oxide(TiO_2) were site-selectively modified with trivalent iron(III)(Fe^<3+>) ions by utilizing adsorption property of iron(III)/ iron(II)(Fe^<3+>/ Fe^<2+>) ions. The rutile TiO_2 with site-selective modification of Fe^<3+> ions showed high photocatalytic activity under visible-light irradiation as a result of separation of redox sites, i. e., oxidation and reduction proceed over Fe^<3+> ions on{ 111} faces and the bare TiO_2 surface on{ 110} faces, respectively.
