Item Catalytic reduction of 2-nitroaniline in aqueous medium using silver nanoparticles functionalized polymer microgel(UMT Lahore, 2024-04-02) FAREEHA AZHARPoly (N-vinylcaprolactam) microgels were synthesized by the free radical precipitation polymerization method in an aqueous environment. Incorporation of silver nanoparticles within the cross-linked network of microgels was carried out through in-situ reduction of silver ions using silver nitrate as a precursor salt. As a result, Ag-p (VCL) hybrid microgels were obtained. In order to analyze the pure and hybrid microgels, different methods of characterization were applied. To ascertain the chemical structure of the pure microgels and hybrid microgels, FTIR was employed. UV-Vis spectroscopy was employed to study the catalytic reduction of 2-Nitroaniline utilizing hybrid microgels as catalyst and NaBH4 as a reducing agent. The catalytic reaction was carried out by studying different parameters by using hybrid microgels in an aqueous media. The apparent rate constant (kapp) for catalytic reduction of 2-Nitroaniline was also calculated. Microgels enriched with silver nanoparticles have the potential to be an effective catalyst in the catalytic reduction of 2-nitroaniline to para-phenylenediamine (p-PDA).
