Abstract

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 1, acid blue 92, acid brown 214, and acid violet 7 [Wastewater colors]. The findings indicated that the amount of Gd₂ZnMnO₆/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 Gd₂ZnMnO₆ and ZnO nanoparticles within the catalyst, which can be reused and recovered for at least 10 cycles without significant loss of reactivity.
