Decolourization of crystal violet using nano-sized novel fluorite structure Ga₂Zr_2-x W _x O₇ photocatalyst under visible light irradiation.

ABSTRACT: Fluorite-type Zr-based oxides with the composition Ga₂Zr_2-x W _x O₇ (x = 0, 0.05, 0.1, 0.15 and 0.2) were prepared using the citrate technique. Appropriate characterizations of all prepared materials were carried out. X-ray diffraction clarified that the undoped and W-doped Ga₂Zr₂O₇ samples were crystallized in the cubic fluorite phase structure. The average particle size of the samples was in the range of 3-8 nm. The lowest band gap (1.7 eV) and the highest surface area (124.3 m² g^-1) were recorded for Ga₂Zr_0.85W_0.15O_7. The photocatalytic impacts of the prepared systems were studied by removal of crystal violet (CV) dye employin
