摘要

Cobalt-doped BiFeO3 nanomaterials were fabricated using the co-precipitation method, and their photocatalytic efficiency is evaluated in treatment of wastewater. The specific pollutant used in this study is methyl orange (MO). The impact of doping on optical, structural, morphological, electrical, and elemental properties is investigated by different concentrations of cobalt ranges from 1%, 3%, 5%, and 7%. These doping concentrations enhanced the crystallinity and layered structure and consequently improved the carrier’s mobility and active sites. These improvised characteristics also boosted the photocatalytic properties of BiFeO3 among all fabricated samples, and 5% cobalt-doped BiFeO3 showed optimal results and degraded the MO dye up to 93%. The recycling and reusability experiment also shows potentials of 5% cobalt-doped BiFeO3 as an efficient catalyst for wastewater treatment application.
