Doping transition metals have great potential to enhance the optical and magnetic properties. This work described the synthesis of pure and FexZr 1-x O2 (x = 0.04, 0.08, and 0.12 mol %) nanoparticles, structural, magnetic, photocatalytic, and anti-microbial properties.  According to the results, Fe doping reduced the crystallite size from 29.74 to 7.88 nm. Smaller particles have a higher surface area-to-volume ratio, which can enhance their reactivity. UV-visible spectra, the produced un-doped, and Fe-doped zirconia nanoparticles have a comprehensive band-gap material ranging between 4.6 and 1.6 eV. A smaller band gap allows nanoparticles to absorb light more efficiently which enhances the photocatalytic activity. The diffraction pattern of pure and Iron-doped ZrO2 nanoparticles reveals a tetragonal crystalline phase. The retention of the tetragonal crystalline structure upon doping, despite introducing Fe3+, highlights a unique stability in the material. The SEM micrograph confirms the Pure ZrO2 nanoparticles have a rod-shaped morphology and spherical mixture of spherical and needle-shaped morphology for iron-doped zirconia with various concentrations. The hysteresis loop for pristine zirconia exhibits perfect Ferromagnetism at Room Temperature (RTFM), whereas iron-doped zirconia exhibits superparamagnetic behavior, according to a VSM investigation which offers several advantages in fields like medicine, and environmental remediation In addition, iron doping improves zirconia’s anti-microbial properties.
