Highly absorption and an excellent optical bandgap of CuO doped Fe nanoparticles for advanced photocatalytic applications.

The sol-gel technique can be used to fabricate purified copper (II) oxide (CuO) and doped Fe nanoparticles. Synthesized nanostructures were examined using XRD, FTIR, UVvisible spectroscopy, SEM-EDX, and vibrating sample magnetometer to determine their crystalline nature, shape, surface area, and elemental composition. Under visible light illumination, photocatalytic evaluations of methylene blue (MB) dye degradation with binary metal oxides were conducted to evaluate the catalyst's recyclability. The photocatalytic degrading of the MB dye pollutant by CuO nanoparticles doped Fe has been shown in detail experiments under visible light irradiation. [ABSTRACT FROM AUTHOR]
