Enhanced Photocatalytic Activities of F Doped Zinc Oxide Nanoparticles by Coprecipitation Method

Fluorine (F) doped ZnO nanoparticles were synthesized by a simple and cost-effective co-precipitation method. The optical and structural properties of the F doped ZnO nanoparticles were investigated. The measured band gap energy of the F doped ZnO nanoparticles showed a blue shift of approximately 0.08 eV in comparison with the bulk band gap energy of 3.33 eV. The wurtzite structure of the produced ZnO nanoparticles was revealed by the XRD results. The crystallite size of the F doped sample was calculated as 11 nm. By degrading the three dyes congo red, rhodamine B, and methylene blue in the presence of the nanocatalysts, the photocatalytic activity of the synthesized nanoparticles has been assessed.
