Efficient and Stable PtFe Alloy Catalyst for Electrocatalytic Methanol Oxidation with High Resistance to CO

Oxyphilic metal Fe is introduced into the Pt lattice to form the PtFe alloy phase and reduces Pt electronic density. PtFe/C with a Pt/Fe atomic ratio of 1:2 possesses small-size PtFe alloy nanoparticles and high dispersion, and has the most excellent methanol electrocatalytic oxidation performance and the highest stability.
