摘要:
以五水硝酸铋(Bi(NO3)3·5H2O)和钛酸四丁酯(Ti(OC4H9)4)为原料,采用水热法,在无表面活性剂的条件下成功制备出不同形貌的Bi12TiO20晶体。利用场发射扫描电镜和X射线衍射仪对产物的微观形貌和晶体结构进行了表征,结果表明,以KOH和NaOH为矿化剂可以分别得到纳米网状和片状的Bi12TiO20晶体,两者属于立方晶系。另外,以模拟太阳光为光源、罗丹明B为目标降解物测试了样品的光催化性能,结果显示,水热合成的Bi12TiO20晶体比固相反应法合成的样品具有更好的可见光光催化性能,其中,基于纳米片状结构Bi12TiO20晶体的罗丹明B溶液,光照180 min后的降解率可达78.2%。
