摘要：

Rhombohedral F-MnTiO3 nanodiscs were synthesized by a facile one-step hydrothermal method using titanate nanowire as Ti source, MnCl2 center dot 4H(2)O as Mn source and NaF as F source without surfactant. The obtained F-MnTiO3 nanodisc was about 1 mu m in diameter and 80 nm in thickness. The element of F, as an electronegative element for electron trapper, enhances the separation ability of photogenerated electron-hole pairs and leads to enhanced photocatalytic activity of F-MnTiO3. The F-MnTiO3 nanodiscs show higher photocatalytic property than MnTiO3 nanodiscs to decompose Rhodamine B under visible light irradiation (C) 2013 Elsevier B.V. All rights reserved.
