Experimental data on synthesis and characterization of WO3/TiO2 as catalyst

WO3/TiO2 is a composite photocatalyst that is being widely used in heterogeneous photocatalysis because it presents better photocatalytic properties than TiO2. For example, the probability of recombination of the electron/hole pairs is diminished and a more range of the solar spectrum is used for it...

Description
Summary:WO3/TiO2 is a composite photocatalyst that is being widely used in heterogeneous photocatalysis because it presents better photocatalytic properties than TiO2. For example, the probability of recombination of the electron/hole pairs is diminished and a more range of the solar spectrum is used for its excitation. However, this depend of variables such as tungsten oxide concentration, calcination temperature and synthesis method. This work is focused in establish the effect of WO3 on the morphological and structural characteristics of TiO2. WO3/TiO2 was synthesized by sol-gel method at different calcination temperatures and at different concentrations of tungsten oxide. The surface area, the possible transition between valence band and conduction band, particle size, elemental analysis and crystallography were examined through the BET, DRS, SEM-EDS and XRD analysis.
