UV- and visible-light-driven TiO2/La2O3 and TiO2/Al2O3 nanocatalysts: synthesis and enhanced photocatalytic activity
The hydrothermal method was used to make the anatase phase of TiO 2 nanoparticles, TiO 2 /La 2 O 3 and TiO 2 /Al 2 O 3 composites. FTIR spectroscopy, X-ray diffraction (XRD), UV–Vis absorption spectroscopy and scanning electron microscopy (SEM) were used to investigate the crystal structure, shape,...
