Abstract

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.
