Description 723-726
This study aims to investigate the structural and optical characteristics of pure α-Fe2O3, ZnO, and α-Fe2O3/ZnO
nanocomposite synthesized by hydrothermal method and their application in the purification of dye-contaminated water.
Synthesized samples were characterized by XRD, UV, and FTIR. XRD pattern of α-Fe2O3/ZnO nanocomposite revealed
two distinct phases corresponding to α-Fe2O3 and ZnO in synthesized nanocomposite. The characteristic absorbance peaks
of α-Fe2O3/ZnO nanocomposite were observed in UV visible spectra with a bandgap of 2.50 eV. The photocatalytic
properties of as-synthesized nanocomposite have been evaluated by photodegradation of methylene blue (MB) under UV
irradiation. Compared to pure metal oxides (α-Fe2O3 and ZnO), photodegradation efficiency of nanocomposite for
methylene blue dye was found to be enhanced. i.e., 78% in 105 minutes. This improved photocatalytic activity can be
ascribed to efficient charge transfer in the nanocomposite, which in turn can be attributed to the reduced recombination
probability of photo-induced carriers. The as-synthesized nanocomposite could be appropriate for wastewater treatment dye.
