This study presents the synthesis and characterization of AgxFe2-xO3 nanoparticles as highly efficient photocatalysts and excellent antimicrobial agents. AgxFe2-xO3 nanoparticle synthesis was carried out through the sol-gel auto-combustion method and was extensively characterized using XRD which confirmed the formation of crystalline -Fe2O3 nanoparticles with crystallite size 22.23 nm and Ag doped Fe2O3 has an average crystallite size 23.08 nm.FTIR provided insights about metal oxide bond formation, and force constant for octahedral and tetrahedral sites which suggest the location of cation and anion. SEM and TEM revealed rhombohedral Ag-doped Fe2O3 nanomaterials with uniform particle size around 20-50 nm which matches with XRD results. UV-Vis spectroscopy shows absorption shifting towards visible light for the AgxFe2-xO3 compared to pristine Fe2O3, indicating the utilization of maximum light spectrum for efficient light harvesting in the visible region. AgxFe2-xO3 exhibited excellent stability and reusability for visible-light-driven photocatalytic dye degradation with a rate constant of 1.27 × 10 -2 min -1 , which is twofold more than that of the pristine Fe2O3 (0.51 × 10 -2 min -1 ). Also, AgxFe2-xO3 was found more efficient in inhibiting the growth of Proteus mirabilis with 16 mm zone of inhibition.
