| Phenol wastewater is one of key controlling objects,which does great harm to environment and becomes a serious problem in environmental protection. Photocatalytic as a new methlod to deal with wastewater in rescent years deeply studied by researcher for its high photo-degradation efficiency,simple technical equipment,operating controlling easily and none secondary pollution caused.TiO2 is one of the promising photocatalysts because of its high photocatalytic activity,high chemical stability,low cost and non-toxicity.However the application of TiO2 only limit to UV(wavelength＜387nm).Therefore,preparation of the catalyst coated as membrane then has been a focus of attention.Hollow TiO2 nanocrystalline with Ag were prepared by silica as a template which systhensised through sol-gel reaction.A series of Ti-SBA-1 mesoporous molecular sieves were directly synthesized under strongly acidic conditions using cetyltriethylammonium bromide as a template.Ag supported on catalysts Ti-SBA-1(Ag/Ti-SBA-1)was prepared by impregnation method.The samples were characterized by TEM,SEM,XRDand N2/adsorption/desorption analysis.The result showed that catalyst Ag/H-TiO2 is 250nm,the sharp of Ag/Ti-SBA-1 like flower and had highly surface areas.Ag hightly dispersed on catalysts.The photocatalytic degradation of phenol-containing water with the sample was investigated with a 6W ultraviolet lamp.The influence of various reaction parameters including reaction time,reactant initialize concentration and Ag content affecting the activity of Ag/Ti-SBA-1 were also studied.Then comparedpu pure TiO2with Ag/TiO2 and Ag/Ti-SBA-1 on degradation ratio.Under the optimized reaction conditions,that is initialize concentration is 6×10-4molL-1,Ag content is 6.7%,PH is 2,the result indicated the Ag can improve photodegredation activity efficienly.After 2h the photodegredation ration of catalyst TiO2,Ag/H-TiO2,Ag/Ti-SBA-1 rearched.68%,100%,70%respectively.
