摘要
The PdCo bimetallic hollow nanospheres with 80 nm average diameter and around 9.0 nm thickness of the shell were prepared with a special reduction method and characterized with transmission electron microscopy （TEM）, X-ray diffraction （XRD） and energy dispersive spectroscopy （EDS）. The electrochemical measurements illustrated that the electrocatalytic activity of the PdCo bimetallic hollow nanospheres for the oxidation of formic acid is much higher than that of the Pd solid nanospheres.
