中文摘要	a high-efficiency nanoelectrocatalyst based on high-density au/pt hybrid nanoparticles supported on a silica nanosphere (au-pt/sio2) has been prepared by a facile wet chemical method. scanning electron microscopy, transmission electron microscopy, energy-dispersive x-ray spectroscopy, and x-ray photoelectron spectroscopy are employed to characterize the obtained au-pt/sio2. it was found that each hybrid nanosphere is composed of high-density small au/pt hybrid nanoparticles with rough surfaces. these small au/pt hybrid nanoparticles interconnect and form a porous nanostructure, which provides highly accessible activity sites, as required for high electrocatalytic activity. we suggest that the particular morphology of the aupt/sio2 may be the reason for the high catalytic activity. thus, this hybrid nanomaterial may find a potential application in fuel cells.
