TiO2-Mn-SBA-15 were prepared by improved after grafting method,using manganese acetate as manganese source,tetra-n-butyl titanate as the titanium source.The catalyst samples were characterized using XRD,low temperature N2 adsorption-desorption.The catalyst was applied to oxidize phenol into hydroquinone under the conditions that the solvent of the reaction is water and under the irradiation of the ultraviolet lamp LED.Ti,Mn loading of the TiO2-Mn-SBA-15,the dosage of the catalyst,reaction temperature and reaction time were investigated to study the effects on the reaction.The results indicated that the conversion of phenol and selectivity of dihydroxybenzene reached 22.7% and 84.7%,respectively,under the optimal reaction conditions(Ti,Mn loading 3%、reaction temperature 30 ℃、reaction time1.5 h、catalyst dosage0.15 g).
