Abstract In a new approach, copper ferrite (CuFe2O4) nanoparticles were easily synthesized using a microwave-ignition reaction and then coated by extracted chlorophyll (extracted from mulberry green leaves) to amplify the photocatalytic and adsorption qualities. The FE-SEM, TEM, Raman, BET, VSM, XRD, EDX and FT-IR techniques were applied to analyze the structure and properties of CuFe2O4 and Chlorophyll/CuFe2O4. The average sizes for nano-catalysts were estimated about 90?nm for CuFe2O4 and 120?nm for Chlorophyll/CuFe2O4. A shift in the band gap from 1.45?eV for CuFe2O4 to 1.3?eV for Chlorophyll/CuFe2O4 exhibited an increase in photocatalytic performance of nanoferrites after coating by the chlorophyll molecules. Photocatalytic degradation studies were performed through UV–Vis technique to measure the removal content of methylene blue (MB) from aqueous samples. The removal efficiency for CuFe2O4 and Chlorophyll/CuFe2O4 were found to be 35.1% and 94.0%, respectively, at certain test conditions. Thereupon, the results confirmed that photocatalytic activity and decomposition capability to remove the MB contaminant increased considerably for chlorophyll coated ferrite. Finally, the nanoparticles were easily separated by an external magnet, reused for several times, and illustrated a negligible decrease in their activity after each cycle.Graphical abstract
