摘要
以Ti(SO4)2和Al2(SO4)3.18H2O为反应物,用乙醇助溶剂水热法制备了TiO2-Al2O3复合光催化剂,考察了铝/钛摩尔比、水热反应温度、乙醇体积分数及pH值对复合材料光催化效率的影响。X射线衍射测试显示复合材料中的TiO2为锐钛矿和金红石相的混晶结构,紫外-可见漫反射光谱分析表明其吸收光谱发生蓝移,BET测试表明该复合材料具有较大的比表面积。
A composite photocatalyst was prepared from Ti（SO4）2 and Al2（SO4）3·18H2O by means of an ethyl-assisted hydrothermal method.The effects of Al/Ti ratio,hydrothermal temperature and ethanol concentration on photocatalytic activity were investigated,and the structures of the samples were signified by XRD.UV-VIS absorption spectra reveal that the samples have blue shift,while BET data show that the composite photocatalyst has a larger surface area.
