عنوان انگلیسی Non-cross-linked Amphiphilic Copolymer Coated Palladium Nanoparticles: A Highly Efficient and Reusable Catalyst for Aerobic Oxidation of Alcohols
چکیده انگلیسی مقاله This work intends to prepare of a non-cross-linked coated palladium nanoparticles. The amphiphilic palladium composite, poly{[3-(acryloylamino)propyl]dodecyldimethylammonium bromide}-co-(N-isopropylacrylamide)12}-Pd, p(ADA-INA)-Pd, was prepared by self-organization of inorganic materials and copolymer, poly{[3-(acryloylamino)propyl]dodecyldimethylammonium bromide}-co-(N-isopropylacrylamide)12}. Anionic inorganic materials self-assembled with non-cross-linked cationic co-polymers were converted into self-organized metal-nanoparticles with polymeric matrixes. The physicochemical properties of the synthesized nanocomposite were characterized by Fourier transform infrared (FT-IR), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The compound p(ADA-INA)-Pd showed the most active catalytic capability in the oxidation of alcohols with high selectivity. The catalytic oxidation of benzyl alcohol, 4-MeO-benzyl alcohol, and 4-Cl-benzyl alcohol with molecular oxygen in acetonitrile and water were investigated. The catalyst could be easily recovered and reused without the change of catalyst structure and significant loss of catalytic activity after each use.
