Abstract
A MnO2/CdTiO3 is prepared by a simple chemical method. The organic compound such as antibiotics is a contaminant found in large amounts in pharmaceutical industrial wastewater. Pharmaceutical compounds are toxic. The nano-product was characterized by SEM, XRD, XPS, DLS and UV-vis DRS revealed that the MnO2 nanoparticles were supported on the CdTiO3 surface. The crystallite size was found as 72.11 nm, and 38.13 nm for CdTiO3, and MnCdTi-1 nanocomposites, respectively. The prepared catalyst was used for photo-degradation of cephalexin under UV light irradiation. The result implies the complete degradation of cephalexin was carried out at 80 min for MnCdTi-2 nanocomposites (88.88%) due to this catalyst has the lowest band gap compared to the other catalyst. The MnO2/CdTiO3 was selected for fungicidal and bactericidal efficiency against Aspergillus flavus, and candida albicans and Escherichia coli, and Staphylococcus aureus. The MnO2/CdTiO3-2 has great activity is compared with the other MnO2/CdTiO3-0 and MnO2/CdTiO3-1 samples.
