摘要: 以凹凸棒土(ATP)作载体,硫酸氧钛、硫酸锌及碳酸铵为原料,采用化学沉淀法制备凹凸棒土负载氧化锌-二氧化钛(ATP/ZnO-TiO2)纳米复合材料,并用XRD,TEM测试手段对样品进行了表征。以其对活性大红(BES)的降解效果作为评价其光催化性能的标准,对制备条件进行了优化。结果表明:ATP与二氧化钛的质量比为20%、二氧化钛与氧化锌的物质的量比为10∶1、煅烧温度为450 ℃下制备的复合材料光催化降解活性大红的效果最佳;与凹凸棒土负载二氧化钛(ATP/TiO2)及凹凸棒土负载氧化锌(ATP/ZnO)相比,复合材料具有良好的可见光光催化性能。

Abstract: Attapulgite loaded zinc oxide-titania (ATP/ZnO-TiO2)nano composite material was prepared by chemical precipitation method with TiOSO4,ZnSO4,and (NH4)2CO3 as raw materials and ATP as carrier.Samples were characterized by XRD and TEM.Photocatalytic activities were evaluated by degradation of activeness scarlet (BES) and the conditions for preparing this composite material were optimized.Results showed that the optimum conditions for preparation of the nano composite material were as follows:mass ratio of ATP to TiO2 was 20%,amount substance ratio of TiO2 to ZnO was 10 ∶1,and calcined temperature was 450 ℃.Under these conditions,the effect of photocatalytic activity of the composite material to BES was the best.Compared with ATP/TiO2 and ATP/ZnO,the nano composite material had better photocatalytic material performance under visible light.
