Abstract: Polymer particles decorated with metal nanoparticles were prepared by UV-irradiation of polystyrene particles incorporating polymethylphenylsilane (PS/PMPS) and P[S-co-NIPAM]/PMPS particles (NIPAM: N-isopropyl acrylamide) in the presence of metal salts. The metal nanoparticle/polymer hybrid particles were used as a catalyst for the reduction of 4-nitrophenol with NaBH 4 . The Pd-and Ag-P(Sco-NIPAM)/PMPS hybrid particles had larger metal nanoparticles and the lower catalytic activity than those of Pd-and Ag-PS/… Show more

“…The deposition of SN on the surface of poly(St) microspheres modified with ClSO 3 H gave nanocomposites, in which the SN are stabilized due to their reaction with the SO 3 H groups of the polymer matrix [92]. The photochemical reduction of Ag + (or Pd 2+ ) ions in the presence of particles of poly(St) or the copolymer of St and IPAAM, containing poly(methylphenylsilane), leads to the deposition of SN on the polymer surface and formation of hybrid catalysts for the reduction of 4NT, whose activity decreases with increasing size of the metal particles [93,94]. Similar materials may also be obtained by grafting of the polymer onto the SN surface [95,96].…”

“…Hybrid composites derived from copolymers of St and its derivatives are also commonly used [34,83,84,[92][93][94][95]. The deposition of SN on the surface of poly(St) microspheres modified with ClSO 3 H gave nanocomposites, in which the SN are stabilized due to their reaction with the SO 3 H groups of the polymer matrix [92].…”

“…16 This kind of deposition on the surface of PS beads can give nanoparticles a superior way to enhance their catalytic performance. 17 PS beads multilayers have been decorated with nickel, 18,19,20 in order to use the magnetic susceptibility and catalytic properties of nickel nanoparticles. The porous monometallic Ni or bimetallic NiFe films can exhibit high magnetic coercivity and square hysteresis compared to thin films.…”
