Nd2Sn2O7 nanoceramic was synthesized using an eco-friendly method with SnCl4•5H2O and Nd(NO3)3•6H2O. Structural analysis confirmed the formation of Nd2Sn2O7 nanoceramic with a size of 20±8 nm. Nd2Sn2O7 was thoroughly characterized using SEM, XRD, TGA, EDX, and TEM techniques. Due to its high mechanical and long-term colloidal stability, large ionic character, and thermal stability, this system is considered an ideal nanocatalyst employing the host-guest approach. This green and environmentally friendly method was tested for the reduction of nitro-aromatic compounds using the synthesized Nd2Sn2O7 nanoceramic. The catalyst demonstrated easy and effective reusability after the reaction was completed under visible light irradiation.

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.
