Advanced Platinum Alloy Electrocatalysts for the Oxygen Reduction Reaction

In the past decade, significant advancement has been made in the development of electrocatalysts for energy conversion and storage. Among various approaches, alloying Pt with 3d transition metals has shown great potential in tailoring the atomic and electronic structures of catalytically active materials toward improved catalytic performance. Here, we provide a brief overview of the recent advancements in the design and synthesis of electrocatalysts for the oxygen reduction reaction. Our focus is placed on the systematic studies of particle size, composition, and shape effect for the monodisperse and homogeneous platinum alloy electrocatalysts that have been synthesized by organic solution approaches.
