The Research of Chemical Plating of Pd/Sn on Graphite Anode Surface and its Electro-catalytic Properties
The Pd/Sn catalytic coating on graphite electrode had been synthesized by chemical plating in this paper.Scanning electron microscope(SEM)and Electrochemical workstation(EW)were used to analyze the coating surface topography and electro-catalytic properties of modified graphite electrode with and without the coating.Results show that Pd and Sn are in the form of spherical particle and completely cover the surface of graphite electrode includes concave defects.Most Pd and Sn particles are dispersive ones of size of about 70 nm and few of which are polymerized in island forms.The peak value of current density increases with scanning speed,which goes positive potential scanning.Further more,the peak current increases with the concentration of NaOH solution,which shows nonlinear relationship between peak current and solution concentration,The peak current increases more rapidly with solution concentration increases in low NaOH concentration solution than that in high NaOH concentration solution.
