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

Copper oxide (CuO) nanorods and cupric tungstate (CuWO4) nanoparticles were prepared by using the hydro thermal 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.

Automated summary

CuWO4/CuO composites prepared by the hydrothermal method showed larger particle size compared to CuO nanorods. The catalytic activity for 4-nitrophenol reduction was significantly increased using these composites, with a higher reaction rate constant observed. The photocatalytic properties under UV light irradiation and significant antibacterial performance were also demonstrated.
