Ag NPs Immobilized on Polymeric Nanocomposite for Metal-Catalyzed Transfer Hydrogenation Reactions

Ag nanoparticles deposited on polymeric nanocomposite TiO2/poly (2-VP-tBuA) were synthesized and characterized by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), Field Emission Scanning Electron Microscopy (FESEM), equipped with an energy dispersive spectroscope (EDS), X-ray diffraction and X-ray photoelectron spectroscopy (XPS). The catalytic efficiency of Ag-TiO2/poly (2- VP-tBuA) nanocomposite was investigated for the reduction of nitro aromatic compounds in the presence of sodium borohydride (NaBH4) as reducing agent in aqueous media and green conditions. Heterogeneous nature of Ag-TiO2/poly (2-VP-tBuA) nanocomposite allows for easy recovery and regeneration, which makes it an attractive system in the context of green and sustainable synthesis
