项目摘要

{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.
{111}形状控制的金红石钛(IV)氧化物(TIO_2)的暴露晶体面孔通过使用三价铁(III)(Fe^<3+>)离子进行位点选择性地修饰,该离子利用铁(III)/铁(III)/铁(II)(II)(II)(II)(II)(II)(II)(II)(II)(II)(II)(II)(II)(II)(II)(II)(II)(fe <3+>/ fe^<2>)。通过氧化还原位点分离,在可见光光照射下,具有Fe^<3+离子的位点选择性修饰的金红石TiO_2在可见光光照射下显示出较高的光催化活性。例如,{111}面上的fe^<3+>离子分别在{110}面上的裸露tio_2表面上进行氧化和还原。
