We have been developed facile and ecofriendly method for the synthesis of Fe3O4 magnetic nanoparticles (MNPs) using an aqueous extract of Pisum sativum peels (PS) is used as reducing and capping agent. The as synthesized PS-Fe3O4 MNPs are characterized by diverse techniques such as FTIR, powder XRD, TEM, BET and Raman spectroscopy measurements. The results show that the obtained Fe3O4 nanoparticles exhibits high specific surface area (similar to 17.6 m(2)/g) and agglomerated spherical in shape with the size range of 20-30 nm. The magnetic properties of PS-Fe3O4 MNPs sample clearly exhibits ferromagnetic nature with a saturation magnetization of 64.2 emu/g. Further, the catalytic properties of PS-Fe3O4 MNPs for degradation of Methyl orange (MO) dye in aqueous solution have been investigated by UV-visible spectroscopy. The results show that PS-Fe3O4 MNPs is an efficient catalyst for degradation of Methyl orange dye than previously reported ones.
