Loading Cu-doped magnesium oxide onto surface of magnetic nanoparticles to prepare magnetic disinfectant with enhanced antibacterial activity

摘要

Graphical abstractDisplay OmittedHighlights?Cu doped MgO was loaded tightly onto magnetic NPs through a hydrophilic carbon layer.?The material showed enhanced antibacterial ability due to the doping of Cu2+in MgO.?The nanocomposite can be easily isolated from aqueous matrix magnetically for reuse.?The magnetic disinfectant has good stability and can be reused for at least 5 times.AbstractIn this article, Cu-doped magnesium oxide was loaded onto the surface of Fe3O4magnetic nanoparticlesviaa hydr
