Synthesis and characterization of Cr2S3–Bi2O3 nanocomposites: photocatalytic, quenching, repeatability, and antibacterial performances

In this study, the bismuth (III) oxide (Bi2O3) nanoparticles and chromium (III) sulphide/bismuth (III) oxide (Cr2S3–Bi2O3) nanocomposites were prepared hydrothermally by sonochemical assisted methods. The different devices such as Scanning Electron Microscopy, UV–vis spectroscopy, dynamic light scat...

Summary:In this study, the bismuth (III) oxide (Bi2O3) nanoparticles and chromium (III) sulphide/bismuth (III) oxide (Cr2S3–Bi2O3) nanocomposites were prepared hydrothermally by sonochemical assisted methods. The different devices such as Scanning Electron Microscopy, UV–vis spectroscopy, dynamic light scattering and, X-ray analysis were used for evaluation of the morphology and structural data of the prepared catalyst. The photo-degra dation activity of Cr2S3–Bi2O3 was comparing with Bi2O3. It was revealed that the Cr2S3–Bi2O3 could raise their photo-degradation performance for the removal of Malathion as an organophosphate insecticide under visible and UV light irradiation. The result from XRD and UV–vis DRS studies were shown the values of crystallite size and band gap for Bi2O3, and Cr2S3–Bi2O3-1 have obtained from and found 50.12, 58.45 nm and 2.81, 2.54 eV, respectively. The optimal condition of Malathion photo-degradation was found at time: 50 min, and pH: 5 for the Cr2S3–Bi2O3-2 with 90.5, and 97.5% photo-decomposition activity after 50 min under visible and UV light elucidation, respectively. The bactericidal possible of the prepared catalyst was appraised by using the disk diffusion proceeding and determining the lowest inhibitory and bactericidal concentration versus the two various bacteria groups. The results demonstrated that Cr2S3–Bi2O3-2 nanocomposites had high antibacterial properties.
