聚合物微球负载金、铂和铑纳米粒子的制备
Preparation of polymer microspheres supported Au, Pt and Rh nanoparticles
摘要
Abstract
Narrow-dispersed Au, Pb and Rh nanoparticles with different size were prepared by in situ reduction of the metallic precursor, with monodispersed Poly (DVB-co-AA), Poly (EGDMA-co-VPy) and Poly (EGDMA-co-HEMA)-SH microspheres as supported. The interaction of the functional groups of the polymers and noble metals were investigated by X-ray Photoelectron Spectroscopy (XPS). The size and morphology of the retained metallic nanoparticles were determined by TEM, which show high distribution on the polymer supporters and narrow-dispersed nanoparticles. The size were dependent on the sort of the functional groups of the polymer microspheres, in another word, the interaction of the polymers with metal atoms. The result showed that the interaction of gaining and losing electrons between different functional groups with metal nanoparticles, making the metal nanoparticles supported on the polymer surface. With respect of the same metal, the stronger the interaction, the bigger the diameter of the nanoparticles;with respect of the same polymer supporter, the larger the electronegativity of the noble metals, the bigger the size of the nanoparticles.关键词
