High-efficiency Palladium Catalysts Supported on Core-shell Ag@C Nanocables for Direct Ethylene Glycol Fuel Cells
In this paper,novel Ag@C nanocables are successfully synthesized through a hydrothermal self-assembled process,and employed as the support material to fabricate uniformly distributed Pd nanoparticle electrocatalyst(Pd/Ag@C)for direct ethylene glycol fuel cells(DEGFC).The morphology and composition of the synthesized Ag@C nanocable support material was determined by the field-emission scanning electron microscopy image(FESEM)and corresponding energy dispersive X-ray spectroscopy(EDS).The results confirm that the obtained nanocable is composed of an inner silver nanowires and an outer carbonaceous layer.According to the transmission electron microscopy(TEM)measurements,the as-prepared Pd nanoparticles are evenly deposited on the surface of the Ag@C without obvious agglomeration,and the average particle size of the Pd nanoparticles is 4.4 nm.Electrochemical measurements demonstrate that the as-prepared Pd/Ag@C catalyst has a better electrocatalytic activity and stability for the oxidation of ethylene glycol.It is concluded that the as-prepared Pd/Ag@C would be a potential candidate as an anode electrocatalyst in DEGFC.
