Effective removal of organic dyes using novel MnWO4 incorporated CA/PCL nanocomposite membranes

The wide range of possible uses of nanocomposite based on metal nanoparticles and polymer-based nanomaterials in many sectors of materials science has drawn more and more interest. Nanocomposites based on cellulose acetate/polycaprolactone (CA/PCL) with manganous tungstate (MnWO4) nanoparticles were synthesized and characterized by SEM, XRD, FTIR, UV–DRS, and XPS. The regular placement of nanoparticles in the CA/PCL/MnWO4 matrix was observed by XRD and SEM investigation. Crystal Violet photocatalytic degradation of the nanocomposite membrane was examined using a UV light source. The photocatalytic efficacy of the CA/PCL/MnWO4 nanocomposites was superior to that of the individual components. The formation of a heterojunction between CA/PCL and MnWO4 with a high charge separation efficiency and powerful UV-light absorption ability was attributed to the enhanced photocatalytic performance. A prospective mechanism for the developed photocatalytic performance was proposed. The present study demonstrated the possible applications of the innovative CA/PCL/MnWO4 photocatalyst for the environment. applications.
