Abstract

Layered material α LiNbWO 6 was prepared by solid state method , HNbWO 6 Fe 1/3 NbWO 6 and HNbWO 6 /Fe 2 O 3 SO 4 2 w ere prepared by the method s such as ion exchange, intercalation and impregnation based on the parent material The phase structures, morphologies, skeleton characteristics and acidic properti e s of the materials w ere characterized by powder X ray diffraction XRD ), scanning e lectron microscope (SEM), f ourier transform infrared spectroscopy (FT IR) and NH 3 temperature programmed desorption ( NH 3 TPD Results show that t he garllery height of the materials var y with the difference interlayer species and t he acid strength follows the order HNbWO 6 /Fe 2 O 3 SO 4 2 HNbWO 6 > Fe 1/3 NbWO 6 HNbWO 6 /Fe 2 O 3 SO 4 2 shows the best catalytic activity and the highest selectivity for toluene nitration ..
