| Abstract: | With Zn(Ac)_2·2H_2O, Fe(NO_3)_3·9H_2O and NaOH as raw materials, Fe~(3+)-doped ZnO was prepared by hydrothermal method. The structure and morphology were investigated by means of X-ray diffrac-tion and scanning electron microscopy. The measurements indicated that the Fe~(3+)-doped ZnO was rod like. The UV diffuse reflectance absorbent properties were detected on a UV-Lambda35 spectrophotometer. The results showed that the Fe~(3+)-doped ZnO had strong absorption in UV and visible regions. Photodegradation of dyes in an aqueous solution was investigated with Fe~(3+)-doped ZnO as a photocatalyst. The results showed that Fe~(3+)-doped ZnO had better degradation properties than pure ZnO. |
