Abstract [en]

A phosphovanadomolybdate hybridized with an anchored dicationic ionic liquid on Al-MCM-41 was prepared through the anion exchange and characterized by 1H and 13C NMR, FTIR, UV?Vis, XRD, XPS, TGA, TEM, FESEM, ICP-OES and BET techniques. The obtained data demonstrated that the composite is a porous material with the high surface area and also having a large pore volume which are 405 m2 g?1 and 0.616 cm3 g?1 respectively. The prepared composite has shown an acceptable catalytic activity for converting benzene selectively to phenol with hydrogen peroxide as eco-friendly oxidant. Under the optimized reaction conditions, the hybrid catalyst resulted in phenol yield of 14.8% with 100% selectivity and a TOF value of 20.0 h?1. The catalyst also revealed a desired recovery and reusability. The efficient performance of the composite is related to the textural and polyoxometalate properties.
