Abstract:

Using Zn(Ac)2•2H2O、Fe(NO3)3•9H2O and NaOH as raw materials, Fe-doped ZnO is prepared by hydrothermal method. The structural and morphology were investigated by means of X-ray diffraction and Scan election microscopy. The measurements indicate that the Fe-doped ZnO is rod. The UV diffuse reflectance absorbent properties are detected by UV-Lambda35 spectrophotometer. The results show that the Fe-doped ZnO has strong absorption at ultral and visible region. Photodegradation of dyes in an aqueous solution is investigated using Fe-doped ZnO as a photocatalyer. The results show that Fe-doped ZnO has better degradation properties than the pure ZnO material.
