摘　　要：为了开发能在光照条件下催化降解有机磷农药的高效、稳定催化剂。以四异烷氧丙基钛为钛源,表面活性剂十二烷基胺为模板剂,采用水热合成法,通过直接嵌入的方式制备了Co掺杂的具有纯锐钛矿型的介孔二氧化钛Co/MTiO2,并用BET、XRD、HRTEM对材料进行了表征并确定了其结构。结果表明,该材料为高度有序、高度热稳定和高比表面积的纯锐钛矿型的介孔二氧化钛材料。在高压汞灯光源的照射下催化降解农药乙酰甲胺磷具有较好的催化活性。该催化剂具有很好的光催化活性和催化稳定性,具有很好的应用前景。In order to develop more efficient and stable catalysts which could be employed to efficiently catalytic degradation of organophosphorus pesticides in light conditions,cobalt-doped mesoporous titania(Co/MTiO2) with anatase crystalline structural wall was prepared by direct incorporation pathway using 1-dodecylamine as structure-directing agent and titanium tetraisopropoxide as titania source.The structures of the material were characterized by BET,XRD,HRTEM.The characterization results indicated that the mesoporous titania with anatase crystalline structure exhibited high ordered mesoporous structure,high thermal stability,high specific surface area and large pore size.Additionally,the material showed good and stable catalytic activity in photo-catalytic degradation of acephate using high pressure mercury lamp as light resource.
