ZnO纳米复合粒子的制备及紫夕吸收性能研究

Preparation of Nanometer ZnO Compound Particles and Research of Ultraviolet Absorption Properties

利用乙醇辅助水热法制备出ZnO／TiO2和ZnO／SnO2两种纳米复合粒子，采用X射线衍射（XRD）、扫描电子显微镜（SEM）及x射线能谱（EDS）分析方法对其结构进行表征，并通过紫外-可见漫反射光谱（uvvis）分析探讨了其紫外可见吸收性能，研究结果表明，在紫外-可见漫反射吸收光谱图中，ZnO／TiO2和ZnO／SnO2纳米复合粒子的最大吸收峰较纯纳米ZnO蓝移。同时，在可见光波段也有较弱吸收，拓展了其紫外吸收光谱。

ZnO/TiO2 and ZnO/SnOe Composite Nanoparticles were prepared by hydrotbermal combined-assisted ethanol method, the products were characterized by using the X-ray diffraction （XRD）, scanning electron microscopy （SEM） and energy dispersive X-ray speetrometer（EDS）, and the uv-vis absorption performance was also characterized by uv-vis diffuse reflective spectrum（UV-vis）. The results of the research showed that, in ultraviolet-visible absorption spectra diffuse, the maximum absorption peaks of ZnO/TiO2 and ZnO/SnO2 nanoeomposite particles were blue shift compared to pure nanometer ZnO, there were also weak absorption in the visible wave band of the absorption, and expanded its UV absorption spectrum.
