| Abstract: | The Pt nanoparticles-filled TiO2-semiconductor nanocomposite samples were prepared. By using SiO2-coated TiO2 nanotube (TiNT@@SiO2) as the support, Pt nanoparticles were successfully filled in TiNT@@SiO2 by a simple UV photoreduction method. The prepared Pt-TiNT@@SiO2 samples were characterized by transmission electron microscopy, field emission scanning electron microscopy, energy dispersive spectrometer, and X-ray diffraction. The photocatalytic activity of the samples for methanol oxidation shows that 1.... |
