Abstract:

Nanocrystalline GaSbO 4 with small particle size and large BET specific area was successfully prepared via a facile hydrothermal method from Sb 2O 5. The influence of the reaction pH on the formation of the final product was investigated. The obtained sample was characterized by X-ray diffraction (XRD), N 2-sorption BET surface area, UV-vis diffuse reflectance spectroscopy (DRS), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM). The photocatalytic activity for the degradations of salicylic acid and acetone over nanocrystalline GaSbO 4 under UV irradiations was for the first time revealed. Based on the electron spin resonance (ESR) result, the reactive species involved in the photocatalytic reaction over nanocrytalline GaSbO 4 are determined to be HO ̇ and O 2 -̇. The photocatalytic mechanism of GaSbO 4 was proposed. © 2012 Elsevier B.V. All rights reserved.
