In this manuscript, we first time report the new generation microgel synthesis without using any divinyl functionalized cross-linker. New generation less crosslinked microgel structure has been achieved by optimizing the amount of N-hydroxy methyl acrylamide (NHMA) and fixed amount of Styrene (St), Acrylic acid (AA) & N-vinyl pyrrolidone (NVP) via free radical emulsion solution polymerization technique. Poly(NHMA) works as a hydrophilic as well as crosslinking agent. Further, microgels have been upgraded into a composite by incorporation of Ag nanoparticles for catalytic reduction applications. Microgels and their composite have been characterized by EDAX, FT-IR, Particle Size Analyzer, SEM, TEM, TGA, UV-Vis. Spectroscopy and XRD (Fig. S3). Methylene blue (MB) dye and p-nitrophenol (PNP) were chosen as model hazardous pollutants for catalytic reduction application. Microgels efficiently adsorb both pollutants over the surface and microgel_Ag composites dramatically reduced both pollutants in the non-toxic form at room temperature by using lesser doses of NaBH4. |
