英文摘要Hyperbranched thin film (htf) with amino and imino groups, which can accommodate ptcl62-, was synthesized with small organic molecules on gold substrate based on sn2 displacement reaction. platinum nanoparticles (pt-nps) were in situ synthesized by electrochemically reduction of precursors, ptcl62-, within htf. the prepared films were characterized by x-ray photoelectron spectroscopy (xps), electrochemical impedance spectroscopy (eis) and atomic force microscopy (afm). it was confirmed that densely packed pt-nps were prepared with a narrow size distribution. eis indicated that htf inhibits electron transfer slightly while pt nanoparticles in the htf enhanced the electron-transfer ability greatly. cyclic voltammetry (cv) indicated that htf containing pt-nps exhibited a remarkable electrocatalytic activity for the electrochemical reduction of dioxygen. the quantity of pt-nps could be expediently controlled by the thickness of htf. so the catalytic ability can be tailored correspondingly.
