| 中文摘要 | in this paper, a simple route for the preparation of pt nanoparticles is described. ptcl62- and [tetrakis-(n-methylpyridyl)porphyrinato] cobalt (cotmpyp) were assembled on a 4-aminobenzoic acid modified glassy carbon electrode through the layer-by-layer method. the three-dimensional pt nanoparticle films are directly formed on an electrode surface by electrochemical reduction of ptcl62- sandwiched between cotmpyp layers. regular growth of the multilayer films is monitored by uv-vis spectroscopy. x-ray photoelectron spectroscopy verifies the constant composition of the multilayer films containing pt nanoparticles. atomic force microscopy proves that the as-prepared pt nanoparticles are uniformily distributed with average particle diameters of 6-10 nm. the resulting multilayer films containing pt nanoparticles on the modified electrode possess catalytic activity for the reduction of dissolved oxygen. rotating disk electrode voltammetry and rotating ring-disk electrode voltammetry confirm that pt nanoparticle containing films can catalyze an almost four-electron reduction of o-2 to water in 0.5 m h2so4 solution. |
