Abstract
In the present study, we adopted, a green approach for the synthesis of ZnFe2O4 nanoparticles using the aqueous flower extract of Nyctanthes arbor-tristis. This extract served as the reducing agent for the synthesis of ZnFe2O4. The obtained nanoparticles were characterized by X-ray diffraction studies which indicated the formation of single phase ZnFe2O4. The size of the nanoparticles was in the range of 4.5–12 nm with calcination temperature as revealed from X-ray diffraction and Transmission electron microscopy, UV-Visible spectroscopy. Photocatalysis studies were made on RhodamineB dye, to assess the degradation capability of the nanopowders calcined at different temperature.
