A series of catalysts,mesoporous molecular sieves(Al-SAB-15) supported copper oxide(CuO/AlSBA-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.
