Surface photoelectric and visible light driven photocatalytic properties of zinc antimonate-based photocatalysts
چکیده انگلیسی

The N-doped and pristine ZnSb2O6 photocatalysts were synthesized by a facile method. The samples were characterized by X-ray diffraction (XRD), UV–vis spectroscopy, surface photovoltage spectroscopy and scanning electron microscopy. The photocatalytic activities of the prepared samples were evaluated from the degradation of rhodamine B (RhB) under full arc and visible light irradiation of Xe lamp. The XRD and UV–vis results indicated that the N-doping did not change the crystal structure, but decrease the band gap in comparison with the pristine one. The N-doped ZnSb2O6 shows the reduced surface photovoltage signals and the significantly enhanced photocatalytic activity under two irradiation conditions.
