在金属盐存在下，通过紫外线照射掺有聚甲基苯基硅烷（PS/PMPS）和P[S-co-NIPAM]/PMPS颗粒（NIPAM：N-异丙基丙烯酰胺）的聚苯乙烯乳胶颗粒，制备了用金属纳米颗粒修饰的聚合物颗粒。金属纳米颗粒/聚合物杂化颗粒用作用NaBH 4 还原4-硝基苯酚的催化剂。 Pd-和Ag-P(S-co-NIPAM)/PMPS杂化颗粒分别比Pd-和Ag-PS/PMPS具有更大的金属纳米粒子和更低的催化活性。聚合物颗粒的表面官能团影响金属纳米颗粒的形成及其催化活性。
Polymer particles decorated with metal nanoparticles were prepared by UV-irradiation of polystyrene latex 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(S-co-NIPAM)/PMPS hybrid particles had larger metal nanoparticles and the lower catalytic activity than those of Pd- and Ag-PS/PMPS, respectively. The surface functional group of the polymer particles affected the formation of the metal nanoparticles and their catalytic activity.
