High temperature self-assembly one-step synthesis of a structurally ordered PtFe catalyst for the oxygen reduction reaction

Abstract

Herein, we present a high-temperature self-assembly strategy that directly allows the transformation of adsorbed Pt(NH3)42+ and Fe3+ sources into structurally ordered face-centered tetragonal (fct)-PtFe alloy NPs (2.6 ± 0.2 nm) by integrating reduction and phase transformation. The small-size and ordered atomic arrangement of the fct-PtFe alloy NPs, together with their robust NC protective shell, make these NPs exhibit excellent catalytic activity and stability for the oxygen reduction reaction.
