Antimicrobial properties of MFe2O4 (M = Mn, Mg)/reduced graphene oxide composites synthesized via solvothermal method.

We herein report the synthesis of MFe2O4 (M = Mn, Mg)/reduced graphene oxide (MFe2O4/RGO) through a simple and novel pressure cooker assisted solvothermal method. The structure and morphology of the as-prepared materials were investigated using X-ray diffraction (XRD), transmission electron microscopic (TEM) and X-ray photoelectron spectroscopy (XPS). The antimicrobial study revealed that the as-synthesized materials displayed good antibacterial effect against E. coli and S. aureus bacteria. In addition, due to the small particle size of MnFe2O4, MnFe2O4/RGO nanocomposite show better antibacterial activity than MgFe2O4/RGO nanocomposite.
