Resumo
A serious of carbon loaded Pd–Cr bimetallic catalysts (PdxCr1–x/C, x = 0.6–1, atomic ratio) were prepared by chemical reduction method. Among them, Pd0.8Cr0.2/C catalyst exhibits the highest catalytic activity for oxygen reduction reaction. Its activity is higher than that of Pd/C and previously reported Pd0.61Cr0.39. Due to the stability of Cr, the Pd0.8Cr0.2/C exhibit excellent durability during electrochemical measurements, which indicates that Pd0.8Cr0.2 is a potential candidate for the cathode of proton exchange membrane fuel cells.
