Abstract

The platinum and rhodium nanoparticles with different sizes were synthesized by in situ reduction of the metallic precursor, supported on the highly crosslinked monodisperse poly(DVB-co-AA), poly(EGDMA-co-VPy) and poly(EGDMA-co-HEMA)-SH microspheres with different functional groups on the surface, which were prepared by distillation-precipitation polymerization. The Pt and Rh nanoparticles were characterized by TEM, which show high distribution on the polymer supporters and narrow-dispersed diameters. The interaction between Pt and Rh nanoparticles and the functional groups of polymer supports were investigated by X-Ray photoelectron spectroscopy (XPS). It is found that the sizes of metallic particles have relationship with the interaction of metals and functional groups and electronegativity of metals: with respect to the same metal, the stronger interaction, the smaller diameter of the nanoparticle; for the same polymer supporter, the larger electronegativity of the noble metals, the bigger size of the nanoparticle.
