Abstract : Cerium-doped copper SHF (CexCu0.5Sr0.5Fe12-XO19) nano material was synthesized by an auto-combustion method using urea fuel. The structural changes upon the substitution of cerium with M-type strontium hexaferrites were evaluated using scanning electron microscopy and FTIR. The PXRD pattern confirmed a crystalline size of 30-36 nm indicates a pure hexagonal crystal structure. Antimicrobial activity tests against Staphylococcus aureus a gram positive and Pseudomonas aeruginosa (Gram negative) bacterial strains demonstrated enhanced antibacterial efficacy in cerium-doped copper strontium hexaferrite samples, which can be attributed to the Ce-mediated redox activity, increased surface reactivity, and the potential for reactive oxygen species (ROS) generation that can be used in producing products with a broad spectrum of antimicrobial activity.

Keywords : Auto-Combustion Method, Antimicrobial Activity, FTIR, Hexagonal Lattice and Scanning Electron Microscopy.
