Article Preview

We study the effect of Mn doping on the photocatalytic photodegradation properties of Zn1−xMnxO nanomaterials to the methyl orange. The Zn1−xMnxO powders and thin films were synthesized by the sol-gel, spin coating and high temperature annealing processes. UV-visible (UV-Vis) spectroscopy was used to examine the radiated and non-radiated samples to study their photocatalytic photodegradation property of the methyl orange. Our results showed that Mn doping can enhance the decolorization efficiency of methyl orange at optimal Mn doping levels, and there exists an optimum Mn doping (x~0.18) at which photodegradation efficiency is nearly optimized.
