Magneto-optical properties of Fe-doped bismuth oxide nanorods for photocatalytic and antimicrobial applications

Abstract

Pure and Fe-doped Bi2O3 nanorods were synthesized using a hydrothermal method and characterized by XRD, FTIR, Raman, FE-SEM, BET, UV–VIS, VSM, and PL. The impact of Fe doping on Bi2O3 causes variation in properties. The 0.5% Fe-doped sample exhibited high surface area (21.732 m2/g) and defects, resulting in exceptional photocatalytic efficiency (93.37%) for Methylene Blue dye degradation under visible light. In addition, their magnetic properties were also investigated, along with observing improved antimicrobial activity. The 0.5% Fe-doped Bi2O3 exhibited a notable 20 mm diameter zone of inhibition against bacteria and 23 mm against fungi, highlighting. This study highlights the versatile potential of Fe-doped Bi2O3 nanorods in photocatalysis and antimicrobial applications.
