dc.description.abstract | We demonstrated the effective reduction of the organic pollutants, the nitroaromatics, via green sustainable chemistry using high efficacy of the catalytic materials, i.e., beta-cyclodextrin (beta-CD) functionalized Au nano -particles (AuNPs). Eco-friendly and biocompatible techniques were employed to fabricate gold nanoparticles (AuNPs) from an Au precursor (HAuCl4) using beta-CD that plays as both reducing and surface-functionalizing agents. Detailed investigation of beta-CD AuNPs formation, their sizes with morphologies, the surface charge, and the hydrodynamic size in a colloidal medium were performed by ultraviolet-visible (UV-vis) absorbance spectroscopy, high-resolution transmission electron microscopy (HR-TEM), Zeta potential measurements, and the dynamic light scattering analysis, respectively. The plasmonic nanoparticle formation of the beta-CD AuNPs led to the strong localized surface plasmon resonance peak at around the 520 nm wavelength. The catalytic activity of the beta-CD AuNPs was evaluated using model reactions, including the catalytic conversion of nitroaromatics to the corresponding amino-aromatic compounds upon mixing sodium borohydride in a water medium. Chemical re-actions of such catalytic reduction of nitroaromatics were tracked by UV-vis absorbance spectroscopy, showing high catalytic activity of beta-CD AuNPs. We also provided a discussion on the possible pathways for the AuNPs-mediated catalytic reduction of nitroaromatics. The efficacy of the nanocatalysts presented to reduce nitro -aromatics can hold a potential promise for detoxifying aquatic environments and their pharmaceutical applications. | - |
