摘要/Abstract

摘要：

ZnO是一种重要的Ⅱ-Ⅵ族半导体材料,其能带宽度约为3.37eV,在光电子学、传感、光催化、发电等诸多领域都具有巨大的应用潜力。本文采用简单的离子交换和热蒸发法成功制备了Fe掺杂ZnO空心微球,并利用扫描电镜、透射电镜、X射线粉末衍射仪对其形貌、结构以及成分等进行了详细的表征。光吸收测试证明Fe元素掺杂能够扩展ZnO的光吸收波段,实现波长375~600nm的光波吸收。另外,光催化实验证明Fe掺杂ZnO空心微球能够有效地促进罗丹明B的降解,表明合成的Fe掺杂ZnO空心微球是一种优异的光催化剂。

Abstract:

As an important Ⅱ-Ⅵ semiconductor, ZnO possesses a band gap around 3.37 eV and shows huge potential applications in optoelectronics, sensing, photocatalysis, electricity generation and so on. In this work, we successfully synthesized Fe doped ZnO hollow microspheres via simple ion exchange and thermal evaporation methods. The morphology, structure and composition of the product have been systematically investigated using scanning electron microscope (SEM), transmission electron microscope (TEM) and X-ray diffraction (XRD). Light absorption measurements indicated that Fe dopants can enhance the light absorption performance of ZnO in light wave band of 375~600 nm. Additionally, photocatalytic characterization demonstrated that Fe doped ZnO hollow microspheres can promote the photodegradation of Rhodamine B, implying that the as-synthesized Fe doped ZnO hollow microspheres are extraordinary photocatalysis.
