| Abstract | ||||
| In this study, Mn2O3 /PVC, Polyvinyl chloride polymer doped with various Mn2O3 nanoparticles, is prepared, and characterized. Solution casting was used to create Mn2O3/PVC polymeric nanocomposite films. The X-ray diffraction method verified that the Mn2O3NPs were effectively disseminated in PVC matrix with a single-phase structure. The casting process is expected to cause Mn2O3 nanoparticles in the PVC matrix to aggregate. According to UV/Vis/IR analysis, the optical energy gap values decrease as Mn2O3 NPs concentration increases. This indicates that complexes of charge transfer between the polymer and Mn+3-ions are developing. Mn2O3/PVC nanocomposite can function as a photocatalyst to enhance the efficiency of Carmine dye photodegradation. The most effective Mn2O3/PVC nanocomposite film for the visible photocatalysis of Carmine dye is 2.5 wt% Mn2O3/PVC. Mn2O3/PVC has been shown to be a promising material for use in photocatalytic, and optoelectronic. | ||||
