摘　　要：设计了一种简单的水热合成法合成晶型可控的立方结构的α-Fe2O3,通过扫描电子显微镜,透射电子显微镜,和X射线衍射对所制备产物的结构和形态特征进行了分析。制备的立方结构的α-Fe2O3的尺寸范围在130150 nm之间。研究结果表明,α-Fe2O3纳米材料作为一种有效的光催化剂,在过氧化氢存在的条件下可以用来光催化降解废水中的有机物（如罗丹明B）,这为设计和开发高效率可见光催化剂在去除工业废水中有机染料的应用提供了新的探索和基础。A simple hydrothermal synthesis method has been designed for the controllable synthesis of cubic α-Fe2O3 nanoparticles.Structural and morphological characterizations of the synthesized products were investigated by scanning electron microscopy（SEM）,transmission electron microscopy（TEM）,and X-ray diffraction（XRD）.The size range of the cubic α-Fe2O3 particles is130150 nm.Results indicate that the α-Fe2O3 nanoparticles can be used as an efficient photocatalysts for photocatalytic degradation of Rhodamine B in the presence of hydrogen peroxide,which may provide the design and development of high-efficiency visible-light photocatalysts for removing toxic dyes from industrial wastewater with a new way and basis.
