| 摘 要： | 本文以羟丙基纤维素(HPC)作为分散剂,运用沉淀法制备出了粒径均匀的ZnO颗粒.通过透射电子显微镜(TEM),X射线衍射(XRD),紫外可见光吸收光谱,光致发光谱(PL)对ZnO进行了性能表征,并探讨了其形成机理及制备中的影响因素.利用纳米ZnO作为光催化剂对有机染料罗丹明B进行了光降解实验,实验结果表明,此方法制备的ZnO具有良好的光催化性能,有望在治理环境污染等领域具有良好的应用.

| Abstract: | The ZnO nanoparticles have been made by precipitation method,and the hydroxypropylcellulose(HPC)was used as protective agent.TEM,XRD,UV-Vis and PL were used to characterize the ZnO nanoparticles.The forming mechanism of ZnO particles and the reaction effect factors were also discussed.Photodegradation of Rhodamine B in aqueous solution was investigated by using the ZnO particles as a photocatalyst.The results show that the ZnO particle is a good photocatalyst for degradation of dye solution.It will have potential applications in many areas such as environment protection. |
