Removal of Organic Dyes Using Gd۲ZnMnO۶/ZnO Ceramic Nanocomposites as a Photocatalysts

The photocatalytic degradation of organic dye residues offers a promising and eco-friendly solution to challenges that endanger living organisms. A highly efficient fibrous nanocatalyst was carefully fabricated, designed, and utilized to remove acid black ۱, acid blue ۹۲, acid brown ۲۱۴, and acid violet ۷ [Wastewater colors]. The findings indicated that the amount of Gd۲ZnMnO۶/ZnO quantum dots affects the degradation efficiency. Integrating quantum dots into the photocatalyst structure boosts light absorption, accelerates electron transfer rates, and enhances charge transfer efficiency. The catalyst's performance was assessed by considering various catalyst components for the removal of organic wastes. The study proposed rational procedures based on the interaction between Gd۲ZnMnO۶ and ZnO nanoparticles within the catalyst, which can be reused and recovered for at least ۱۰ cycles without significant loss of reactivity.
