Synthesis of ag/cu-fe3o4 nanocomposite shows high selectivity in reducing nitroaromatic compounds, suggesting potential for green chemistry applications.
This study reports the synthesis of Ag/Cu-Fe3O4 nanocomposite, using a naturally occurring amino acid L-arginine as a linker and its catalytic application to reduce nitroaromatic compounds to aminoaromatic compounds. Decoration of Cu and Ag nanoparticles on Fe3O4 NPs created the Ag/Cu-Fe3O4 nanocomposite. Advanced characterization techniques confirmed the composition and morphology of the synthesized nanocomposite. The catalytic performance of Ag/Cu-Fe3O4 nanocomposite was evaluated using UV-visible spectrophotometry for NaBH4 assisted reduction of 4-nitrophenol to 4-aminophenol and 5-nitroisophthalic acid to 5-aminoisophthalic acid. After multiple cycles, results demonstrated that nanocomposite facilitates rapid and efficient chemical transformations with high selectivity and over 80% efficiency. Additionally, the nanocomposite’s capability for easy magnetic recovery and recyclability underscores its potential as a cost-effective and environmentally friendly solution for industrial applications in sensing, catalysis and green chemistry. This work presents a novel strategy for converting nitroarenes to aminoarenes, leveraging unique synergetic properties of Ag/Cu-Fe3O4 nanocomposite.
