Abstract:
Al substituted FeVO4 catalysts were prepared by co-precipitation method. The catalysts were characterized by X-Ray Diffraction, Brunauer-Emmett-Teller surface area analysis, Thermo gravimetric-Differential thermal analysis, scanning electron microscopy, transmission electron microscopy and X-ray photoelectron spectroscopy. The Al content increased the acidic character of the catalyst. The catalytic activity was evaluated for methylation of phenol and showed high activity and selectivity. 2 percent Al promoted FeVO4, caused the conversion of phenol and selectivity towards 2,6-xylenol to reach 98 percent and 94 percent respectively. The catalyst has good stability, TOS studies and characterization of spent catalyst was done.
