摘要
采用溶剂热法,以硝酸铁为铁源,十六烷基三甲基溴化铵为表面活性剂,合成了α-Fe_2O_3纳米颗粒。采用X-射线粉末衍射(XRD)、扫描电子显微镜(SEM),透射电子显微镜(TEM)对样品进行了分析。把α-Fe_2O_3纳米颗粒用于光催化降解有机染料罗丹明B,并和商业Fe_2O_3粉体比较,结果发现,α-Fe_2O_3光催化活性明显高于商品Fe_2O_3粉体。
The α-Fe_2O_3 nanoparticles were synthesized using ferric nitrate as Fe source and hexadecyltrimethylammonium bromide as surfactant by a simple solvothermal route,without any template or subsequent calcination.The as-obtained products were characterized by X-ray diffractometer（XRD）,scanning electron microscopy（SEM）and transmission electron microscopy（TEM）.The photocatalytic activity of products was evaluated by photodegradation of RhB dye solution under UV light,and comparing with commercial hematite powder.The results showed that the photocatalytic activity were much higher than that of the commercial hematite powder.
