Synthesis of Self-Organized Polycrystalline F-doped TiO2 Hollow Microspheres and Their Photocatalytic Activity under Visible Light
Abstract
A wet-chemistry method was used to dope F - ions into crystalline TiO 2 by hydrothermal treatment of TiF 4 in an HCl solution. Field-emission electron microscope and transmission electron microscope images showed that the products exhibited a flowerlike morphology with a hollow interior. X-ray photoelectron spectroscope data demonstrated the doping of F in the lattice of crystalline TiO 2 . The flowerlike F-doped TiO 2 hollow microspheres synthesized at 180 °C showed the highest photocatalytic activity for the degradation of methylene blue under visible light irradiation. Ostwald ripening is the main reason responsible for the formation of the hollow interior of the F-doped TiO 2 micropheres, and the HF species generated from the hydrothermal reaction is believed to accelerate the formation of the TiO 2 hollow spheres.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
