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 (Li 0.5 Fe 2.5 O 4 ), lithium-magnesium ferrite (LiMg 0.5 Fe 2 O 4 ) and lithium-nickel ferrite (LiNi 0.5 Fe 2 O 4 ) are nano-photocatalytic samples, which are in good crystalline form. The LiMg 0.5 Fe 2 O 4 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 LiNi 0.5 Fe 2 O 4 nano-photocatalyst decreases with doping Ni or Mg. Finally, in vitro cytotoxic effect of synthesized nanoparticles was evaluated on Hela cell line.
