| 英文摘要 | A defect pyrochlore-type Sn1.06Nb2O5.59F0.97(SnNbOF) nano-octahedron is used as a redox-active support for fabricating Au@SnO(2)core-shell and SnO(2)quantum dots at room temperature without the use of organic species or foreign reducing reagents. Gold (Au) and SnO(2)components were obtained through anin situredox reaction between the HAuCl(4)and reductive Sn(2+)ions incorporated in SnNbOF. The composition and morphology of the resulting nanocomposites (denoted as Au-SnNbOF) could be controlled by adjusting the Au/SnNbOF ratio. The Au-SnNbOF nanocomposites exhibited efficient photoactivities for methyl orange (MO) degradation under the visible light irradiation (lambda> 420 nm), during which the MO was almost completely degraded within 8 min. Among all the samples, the 5wt% Au-SnNbOF nanocomposite had the highest rate constant (0.43 min(-1)), which was 40 times higher than that of the blank SnNbOF. |
