Abstract

Visible-light-induced BiVO4 was prepared by hydrothemal method and characterized by XRD, SEM and UV–vis spectroscopy. The characterization indicated that photocatalyst had better structure. The result indicated that tthe BiVO4 sample synthesized at 140℃ and 2h was monoclinic phase with a 0.5μm of average particle sizes, and exhibited strong absorption in the visible light region. The photocatalytic properties of the BiVO4 samples were evaluated by removing thiophene in n octane, the result showed that the BiVO4 sample exhibited higher photocatalytic desulfurization, and the removal of thiophene of the mode compound in the visib le light/H 2 O 2 /BiVO 4 system wawas in three steps..
