Synthesis of F doping MnTiO3 nanodiscs and their photocatalytic property under visible light
Rhombohedral F-MnTiO3 nanodiscs were synthesized by a facile one-step hydrothermal method using titanate nanowire as Ti source, MnCl2·4H2O as Mn source and NaF as F source without surfactant. The obtained F-MnTiO3 nanodisc was about 1μm in diameter and 80nm in thickness. The element of F, as an elec...

Summary: | Rhombohedral F-MnTiO3 nanodiscs were synthesized by a facile one-step hydrothermal method using titanate nanowire as Ti source, MnCl2·4H2O as Mn source and NaF as F source without surfactant. The obtained F-MnTiO3 nanodisc was about 1μm in diameter and 80nm 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.
Rhombohedral F-MnTiO3 nanodiscs were synthesized by a facile one-step hydrothermal method. F-MnTiO3 showed more than 40% of higher photocatalytic efficiency than MnTiO3 under the same condition. The element of F, as an electronegative element for electron trapper, restrained combination of photogenerated electron–hole pairs and leaded to enhanced photocatalytic activity of F-MnTiO3.
