Abstract

Abstract: A series of catalysts, mesoporous molecular sieves(Al-SAB-15) supported copper oxide(CuO/Al-SBA-15) with different copper content and Si/Al mass ratios, was characterized by small X-ray diffraction, N2 adsorption-desorption and the catalytic activity in the phenol hydroxylation reaction. The mesostructure was found to become disordered with the copper content increasing. High catalytic conversion up to 61.2% was achieved with 3% copper. A 57.9% conversion for the phenol hydroxylation with the catalyst supported on Al-SAB-15 is higher than the 43.6% conversion with the catalyst supported on SBA-15 after 5 recycles. This may be attributed to the increased surface charges associated with Al cations and the resulted uniformly dispersed Cu.

Key words: phenol hydroxylation, mesoporous molecular sieves, CuO/Al-SBA-15
