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 Pt_(0.65_Co_(0.35)/C,Pt/C,Pd_(0.65)Co_(0.35)/C and Pd/C catalyst,Pt_(0.35)Pd_(0.35)Co_(0.30)/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 Pt_(0.35)Pd_(0.35)Co_(0.30)/C exhibited excellent activity with higher current density and higher CO tolerance than that of Pt_(0.65)Co_(0.35)/C,Pt/C,Pd_(0.65)CO_(0.35)/C,and Pd/C in formic acid electro-oxidation.
Pt: Pd: Conary 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 Pt_ (0.65_Co_ (0.35) / C, Pt / Pd 0.65 Co 0.35 / C and Pd / C catalyst, Pt 0.35 0.35 0.35 Co 0.30 / C indicates relatively high durability and strong poisoning resistance, and the Pt-mass activity was 3.6 times higher than the Pt_ (0.35) Pd_ (0.35) Co_ (0.30) / C showed excellent activity with higher current density and higher CO tolerance than that of Pt_ (0.65) Co_ (0.35) / C, Pt / C, Pd_ (0.65) CO_ (0.35) / C, and Pd / C in formic acid electro-oxidation.
