PtFeCu Concave Octahedron Nanocrystals as Electrocatalysts for the Methanol Oxidation Reaction
journal contribution
posted on 2019-12-13, 19:27 authored by Yuanyuan Zhang, Rui Shi, Jing Ren, Yang Dai, Yijie Yuan, Zhenghua WangIn this work, PtFeCu concave octahedron nanocrystals
were synthesized
by a one-pot solvothermal method. The PtFeCu concave octahedron nanocrystals
were applied as an electrocatalyst for the electrooxidation of methanol
and have shown high electrocatalytic activity and long-term durability.
The electrocatalysis performances of the PtFeCu concave octahedron
nanocrystals are better than those of the PtFe and PtCu nanocrystals
and commercial Pt/C. The synergistic effect of the Pt, Fe, and Cu
metals and the unique concave octahedron morphology may be the main
cause of the superior electrocatalytic performances of the PtFeCu
nanocrystals. The PtFeCu concave octahedron nanocrystals have a potential
application as an anode catalyst for direct methanol fuel cells.
