Hydrothermal-ultrasonic synthesis of CuO nanorods and CuWO4 nanoparticles for catalytic reduction, photocatalysis activity, and antibacterial properties

Abstract Copper oxide (CuO) nanorods and cupric tungstate (CuWO4) nanoparticles were prepared by using the hydrothermal method process by calcination progress. The particles size of CuWO4/CuO composites was larger than that CuO nanorods. A suggested reaction mechanism was depicted. The product indicated substantial catalytic activity for 4-nitrophenol reduction. The reaction rate constant enhanced from 0.382 min−1 to 0.659 min−1 by using the CuO nanorods and CuWO4/CuO composites, respectively. The photocatalytic properties of the prepared materials was examined by using the degradation of f 4-nitrophenol under UV light irradiation. The CuWO4/CuO nanocomposites indicated significant antibacterial performance in the disc diffusion analysis.
