Abstract The hollow microspheres containing monoclinic scheelite BiVO4 and anatase TiO2 nanocrystals were easily prepared through a simple one-step template-free method. Bi(NO3)3H2O and NH4VO3 were used as BiVO4 precursor and (NH4)2TiF6 as TiO2 precursor to produce the target products in the presence of glucose under the high temperature pyrolysis. The products were characterized with SEM, XRD, TEM and UV-vis DRS. The as-prepared hollow microspheres showed high photocatalytic activity, which was demonstrated by degradation of acetic acid solution under visible-light irradiation ( >420 nm).
