Curd Mediated Facile Synthesis of ZnO/Ag/NiO Heterostructures and
Visible Light Assisted Photodegradation of Methylene Blue
Green fuel perished curd was used to synthesize ZnO/Ag/NiO ternary heterostructure with zinc nitrate, nickel carbonate and silver nitrate as oxidizers. The obtained nanostructure was characterized by various analytical techniques such as powder X-ray diffraction (PXRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (FESEM), transmission electron microscopy (TEM). The particles and flakes composition of ZnO/Ag/NiO nanomaterials was confirmed. Photocatalytic activity of ZnO/Ag/NiO was evaluated with methylene blue dye by source of light, concentration of hydrogen ion, catalyst and dye concentrations. The obtained ZnO/Ag/NiO nanoparticles reveal better catalytic property for the photodegradation of methylene blue dye under visible light.
