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...

TiO2 nanomaterials with controlled morphologies have attracted extensive interest because of potential applications in solar energy conversion, environmental cleanup and hydrogen generation. Nanoscale titanium dioxides have been produced as nanotubes, nanosheets, nanowires and mesoporous microspheres by a variety of approaches. Among the various nanomaterials, mesoporous microspheres have drawn...

Abstract In this work, Nickel (Ni) and sulfur (S) codoped TiO 2 nanoparticles were prepared by a sol-gel technique. The as-prepared catalyst was characterized using X-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FTIR), FT-Raman spectroscopy, scanning electron microscopy (SEM), energy dispersive spectrometer (EDS), transmission (TEM), UV-Vis diffuse reflectance spectra (DRS) ...
