摘要
采用鸡蛋清作为纳米反应器,聚乙烯吡咯酮(PVP)作稳定剂,通过水热法合成了扇状纳米氧化锌。通过XRD、SEM、TEM、FT-IR、UV-Vis等分析方法对样品进行了表征,考察了样品对甲基橙溶液的光催化降解的性能,并初步讨论了这种扇形结构纳米氧化锌的形成机理。结果表明:该方法能简单、快速制备扇状纳米氧化锌材料,且得到的扇形样品具有很好的光催化性能。
Absstract：Fan-like nano-sized zinc oxide were synthesized by hydrothermal process, using egg albumin as nanoreactor and polyvinylpyrrolidone （PVP） as stabilizer.The samples were characterized by X-ray diffraction （XRD）,scanning electron microscope （SEM）, transmission electron microscopy （（TEM）, Fourier transform infrared （FT-IR）, and ultraviolet visual （UV- Vis） spectroscopy.The photocatalytic activity of the sample was also investigated by degradation of methyl orange. Furthermore,the formation mechanism of fan-like nano-sized zinc oxide was discussed in detail.Results showed that the method is a facile, effective way to synthesize fan-like nano-sized zinc oxide material and the obtained product has a good photocatalytic activity. Key words： zinc oxide ; nanomaterial ; hydrothermal ; photocatalysis
