Simple synthesis and characterization of Li0.5Fe2.5O4, LiMg0.5Fe2O4 and LiNi0.5Fe2O4, and investigation of their photocatalytic and anticancer properties on hela cells line

In the present work, the anticancer, photocatalytic and magnetic qualities of nanocrystalline nickel or magnesium-doped nanoparticles of lithium-ferrite samples, formed through sol-gel auto-combustion process were investigated. The products were studied by FT-IR spectroscopy, scanning electron microscopy (SEM), energy dispersive X-ray (EDX) technique, X-ray diffraction (XRD), ultraviolet-visible diffuse reflectance spectroscopy (DRS), photoluminescence (PL) spectra, and vibrating sample magnetometery (VSM). XRD results showed that the nano-photocatalytic samples lithium ferrite (Li0.5Fe2.5O4), lithium-magnesium ferrite (LiMg0.5Fe2O4) and lithium-nickel ferrite (LiNi0.5Fe2O4) are nano-photocatalytic samples, which are in good crystalline form. The LiMg0.5Fe2O4 nano-photocatalyst showed the highest photocatalytic performance for removal of methyl orange (MO) and removed 99.9% of pollutant within 25 min under ultraviolet (UV) light irradiation. Magnetic characterization revealed that the M-r and M-s of LiNi0.5Fe2O4 nano-photocatalyst decreases with doping Ni or Mg. Finally, in vitro cytotoxic effect of synthesized nanoparticles was evaluated on Hela cell line.
