摘要
采用NAC-FAS工艺直接制备了不同掺杂比例的纳米Fe掺杂Zn O样品,利用SEM和UV-Vis等方法对样品的结构及光学性质进行了表征。结果表明:在89℃下,以二水合乙酸锌、氢氧化钠、三氯化铁为出发原料,在醇水溶液体系中直接合成了Fe掺杂纳米Zn O,Fe的掺杂没有引入新的杂相。随着Fe掺杂比例的增加Zn O的光催化活性增加,当Fe掺杂比例为9%时的Fe-Zn O纳米晶光催化活性最优。
The samples of nanometer Fe-ZnO with different doping concentration were direct prepared by NAC-FAS method. The structure, morphology and optical properties with Fe-ZnO were examined by X-ray diffraction, scanning electron microscope and UV-Vis spectrophotometer. The results showed that Fe-doped nanometer ZnO with hexagonal wurtzite structure was prepared without any secondary phases below 89℃ in ethanol-water solution, Zn（Ac）2 · 2H2O, NaOH and FeCI3 as the starting material. The photocatalytic activity of Fe-ZnO increased with the increase of the proportion of Fe ion. The photocatalytic properties of Fe-doped ZnO was better than others when the proportion of Fe ion was 9%.
