Pt:Pd:Co ternary alloy nanoparticles were synthesized by sodium borohydride reduction under nitrogen, and were supported on carbon black as catalysts for methanol and formic acid electro-oxidation. Compared with Pt0.65Co0.35/C, Pt/C, Pd0.65Co0.35/C, and Pd/C catalyst, Pt0.35Pd0.35Co0.30/C exhibited relatively high durability and strong poisoning resistance, and the Pt-mass activity was 3.6 times higher than that of Pt/C in methanol oxidation reaction. Meanwhile, the Pt0.35Pd0.35Co0.30/C exhibited excellent activity with higher current density and higher CO tolerance than that of Pt0.65Co0.35/C, Pt/C, Pd0.65Co0.35/C, and Pd/C in formic acid electro-oxidation.
Pt0.35Pd0.35Co0.3/C was prepared as catalysts in methanol and formic acid electro-oxidation, and it exhibited higher catalytic activity and durability than Pt0.65Co0.35/C, Pd0.65Co0.35/C, Pt/C and Pd/C catalysts.Figure optionsDownload as PowerPoint slide
