Stabilization of silver nanoparticles in crosslinked polymer colloids through chelation for catalytic degradation of p-nitroaniline in aqueous medium

Abstract

Abstract Poly (N-isopropylacrylamide-2-hydroxy ethyl methacrylate-acrylic acid) [P(NHA)] colloidal particles of core-shell morphology were obtained by free radical emulsion polymerization. Loading of Silver nanoparticles within P(NHA) colloidal particles was attained by in-situ reduction. P(NHA) and Ag-P(NHA) particles were characterized by UV-Vis and TEM. For probing catalytic ability of Ag-P(NHA) hybrid particles, catalytic reduction of 4-Nitroaniline (4-NA) was carried out as an exemplary reaction. Ag-P(NHA) hybrid particles served as an exceptional nano-catalyst for reduction of 4-NA. Comparison of current study with academic literature proves that our system provides rapid and simple approach for efficient and cost-effective reduction of 4-NA in aqueous condition.
