中文摘要	novel au-pt bimetallic flower nanostructures fabricated on a polyamidoamine dendrimers-modified surface by electrodeposition are reported. these polyamidoamine dendrimers were stable, and they assisted the formation of au-pt bimetallic nanoflowers during the electrodeposition process. these nanoflowers were characterized by field-emitted scanning electron microscopy (fe-sem), energy-dispersive spectroscopy (eds), x-ray photoelectron spectroscopy (xps), x-ray diffraction, and electrochemical methods. fe-sem images showed that the bimetallic nanoflower included two parts: the "light" and the "pale" part. the two parts consisted of many small bimetallic nanoparticles, which was attributed to the progressive nucleation process. moreover, the "light" part contained more bimetallic nanoparticles. the morphologies of bimetallic nanoflowers depended on the electrodeposition time and potential and the layer number of assembled dendrimers. the average size of nanoflowers increased with the increase in electrodeposition time. the layer number of assembled dendrimers obviously affected the size and morphologies of the "pale" parts of deposited nanoflowers.
