Copper oxide nanoparticles-decorated cellulose acetate: Eco-friendly catalysts for reduction of toxic organic dyes in aqueous media.

In this study, we aimed to gain insight into the potential of catalytic reduction using copper oxide nanoparticles decorated cellulose acetate as a biosupport (CuO@CA) for the removal of specific pollutants. The prepared catalyst was submitted to a series of spectroscopy techniques for characterization purposes. The results of the catalytic tests on methylene orange (MO) and methylene blue (MB) solutions suggest that the elimination efficiency may be influenced by several factors, including the catalyst dose and the concentration of the pollutant.
