The chemical structure of synthesized (p(AN-co-APTMACl)) macroporous hydrogel was confirmed by Fourier Transform Infrared (FT-IR), scanning electron microscopy (SEM). P(AN-co-APTMACl) has been successfully utilized for the in situ synthesis and stabilization of silver nanoparticles within the hydrogel matrix. These hydrogel composites were characterized by Fourier transform infrared (FT-IR), field-emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM) and atomic absorption spectroscopy (AA). The morphology of the p(AN-co-APTMACl) reveals the formation of homogeneous and highly porous material. Catalytic activity of p(AN-co-APTMACl)-Ag catalyst was investigated in the aerobic oxidation of olefins, reduction of 4-nitrophenol and hydrolysis of sodium borohydride by emphasizing the effects of different parameters such as temperature, substituent effect, etc. The catalyst was easily recovered from the reaction medium and it could be re-used for other five runs without significant loss of activity.}, keywords = {Co-polymer,acrylonitrile,Cationic hydrogels,Reusable,Nanocomposites}, url = {http://www.nanochemres.org/article_127146.html}, eprint = {http://www.nanochemres.org/article_127146_7001c13544cfa6b558a476d58517c7d4.pdf} }
