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.
•The nano-catalyst were synthesized by hydrothermal-ultrasonic method.•The nano-catalyst having particle size around 58, and 66 nm.•The product showed excellent catalytic performance for 4-nitrophenol reduction.•The nano-samples have a great antibacterial activity.
