环化聚丙烯腈修饰氧化锌的紫外光催化性能

为了提高ZnO的光催化性能，采用浸渍法制备环化聚丙烯腈（CPAN)修饰ZnO纳米复合微粒。通过X射线衍射法（XRD)、透射电镜（TEM)和X射线光电子能谱（XPS)等手段，对ZnO/CPAN纳米复合微粒及ZnO纳米微粒的粒径、晶型及结构进行了表征。利用甲基橙为模型污染物，紫外灯为光源，研究了ZnO/CPAN的紫外光催化性能。光催化实验结果表明，CPAN修饰ZnO可以显著提高其紫外光催化活性，ZnO/CPAN质量比为1000:1、热处理温度为150°C、热处理时间为30min时，光催化活性最强。...

In order to improve the photocatalytic properties of ZnO, the cyclized polyacrylonitrile(CPAN) modified zinc oxide (ZnO) nanocomposites are prepared by impregnation method. The size,morphology, internal structure of ZnO/CPAN nanocomposite and ZnO nanoparticles are characterized by means of X-ray diffraction ( XRD), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). The UV-light photocatalytic activity of ZnO/CPAN is evaluated with methyl orange as model pollutant under UV-light irradiation. The results of photocatalytic experiment show that the CPAN modified ZnO can significantly improve the UV-light photocatalytic activity of ZnO particles. When the mass ratio of ZnO/CPAN is 1 000 : 1, the heat treatment temperature is 150 °C , and the heat treatment time is 30 min, the photocatalytic activity is the highest.
