Synthesis And Characterization Of Zno-Cdo Nanocomposite And Its Antibacterial Activity

Abstract

Adopting a new synthetic approach for nanoparticles and nanocomposites will improve nanoscale materials science and technology. A unique microwave aided approach was used to produce ZnO (zinc oxide)-CdO (cadmium oxide) nanocomposite in this study. For the creation of nanocomposites and nanomaterials, the microwave-assisted method is the most efficient time and energy efficient technique. The synthesis of ZnO- CdO Nanocomposite was ensured by a strong peak at 380 nm caused by UV absorption. Fourier The bonding nature of the samples was investigated using a FT-IR (Fourier transform infrared) spectrum analysis. The distinctive stretching mode of the Zn–O/Cd-O bond was ascribed to a prominent band in the FTIR range of ~ 3510 to 1624 cm1. XRD was used to characterize the structure of the metal oxides and nanocomposites as they were synthesized. The normal crystallite size of the ZnO-CdO nanocomposite was calculated to be around 27.26 nm using Debye's Scherrer equation and FWHM data. SEM and TEM tools were used to examine the morphology of the samples as they were prepared. For the combined effect, SEM and TEM images exposed that the standard particle size of the ZnO-CdO nanocomposite was 50 nm, and it had a spherical form. A study of the nanoparticles' antioxidant activities demonstrated that, in comparison to their minimum inhibitory concentration (IC50) values, ZnO-CdO nanocomposite showed superior scavenging capability.The antibacterial activity of the synthesized ZnO-CdO nanocomposite against Staphylococcus aureus, Bacillus subtilis, Klebsiella pneumoniae and E. coli bacteria was investigated, and it was found to be superior to that of the standard medication and CdO alone.Prepared ZnO nanoparticle and ZnO-CdO were also discovered to have exceptional photocatalytic activity against the degradation of methylene blue when exposed to sunlight, with a value of 60 and 50 minutes, respectively.
