Novel polyvinyl alcohol-assisted MnO₂-ZnO-CuO nanocomposites as an efficient photocatalyst for methylene blue degradation from wastewater.

ABSTRACT: Pristine ZnO (Z), MnO₂ (M), CuO (C) photocatalysts and polyvinyl alcohol (PVA)-assisted MnO₂-ZnO-CuO (MZC) nanocomposites were synthesized via the sol-gel method. The synthesized samples were characterized using thermal analysis (TGA), X-ray diffraction (XRD), dynamic light scattering (DLS), scanning electron microscopy (SEM), energy dispersive X-ray (EDS), transmission electron microscopy (TEM), and high-resolution transmission electron microscopy (HRTEM) techniques. The thermal analysis results of the prepared nanomaterial confirmed that the suitable calcination temperature for the synthesis of these nanomaterials is 420 °C. In addition to the morphological and elemental composition, the characteristic diffraction peaks of the MZC nanomaterial were found to a
