Nb, F-codoped TiO2 hollow spheres with high visible light photocatalytic activity
Nb, F-codoped TiO2 hollow spheres (NFTSs) were successfully synthesized via a hydrothermal method with niobium oxide, hydrofluoric acid, and tetrabutyl titanate. The obtained spheres were hollow, with a diameter of about 2 μm, and the sphere wall was made up of nanorods arranged close together. The NFTSs presented anatase phase with more {001} facets exposed, which could be mainly attributed to...
متن کاملPreparation and Visible-light Photocatalytic Activity of Pt/TiO2-xNy
Pt/TiO2-xNy film has been synthesized successfully through the sol-gel method and spin coating method. The roughness and absorption wavelength were analyzed by atomic force microscopy (AFM) and ultraviolet and visible spectrophotometer(UV-vis). X-ray photoelectron spectroscopy(XPS) showed that the elements contain Pt, N, Ti and O. Moreover, the photocatalytic degradation of methylene blue demon...
متن کاملQuick and Facile Preparation of Visible light-Driven TiO2 Photocatalyst with High Absorption and Photocatalytic Activity
Self-doping TiO2 has recently attracted considerable attention for its high photocatalytic activity under visible-light irradiation. However, the literature reported synthetic methods until now were very time-consuming. In this study, we establish a quick and facile method for obtaining self-doping TiO2 with the use of directly treated commercial P25 at a desired temperature for only 5 min thro...
متن کاملAdsorption-assisted photocatalytic activity of nitrogen and sulfur codoped TiO2 under visible light irradiation.
Applying post thermal treatment on the doped TiO2 at high temperature is mostly regarded as an indispensable process, although it has negative effects on the photocatalytic activity of doped TiO2. Herein, we synthesized the N- and S-codoped TiO2 (NSTs) with an anatase phase using a simple solvothermal treatment and investigated their visible light photocatalytic activity associated with the the...
متن کاملA visible light driven doped TiO2 nanophotocatalyst: Preparation and characterization
A useful nanophotocatalyst (La,S-TiO2) was prepared by a sol-gel method and characterized by UV–vis diffuse reflectance spectroscopy (DRS), X-ray diffraction (XRD), photoluminescence emission spectroscopy (PL) and scanning electron microscopy (FESEM). The results showed that the La,S-TiO2, which calcined at 550 °C, contained only anatase phaseand its crystal size was 23 nm...
