ZnO/Ag/MnO ternary heterostructure nanomaterials have been synthesized via cost effective greenroute using zinc nitrate, manganese acetate and silver nitrate as oxidizers and perished curd as a fuel.The obtained ZnO/Ag/MnO nanomaterials are analyzed using Powder X-ray diffraction (PXRD),Fourier transform infrared spectroscopy (FTIR), morphological studies by scanning electron microscopy(FESEM), internal structure by transmission electron microscopy (TEM). Both PXRD and FESEMtechniques were used to confirm the formation of particles and flakes composition of ZnO/Ag/MnOnanomaterials. Photocatalytic activity of ZnO/Ag/MnO was assessed by varying light source, hydrogenion concentration, amount of catalyst and amount of dye. The ZnO/Ag/MnO nanoparticles exhibitedan enhanced photodegradation of methylene blue dye under visible light.
