Multimetallic Electrocatalyst Stabilized by Atomic Ordering

The absence of low-platinum, high-activity, and satisfied-durability electrocatalysts for oxygen reduction reaction has bottlenecked the wide adoption of proton exchange membrane fuel cells for decades. In this issue of Joule, Sun and coworkers introduce a class of atomic-ordering L1 0 CoPt electrocatalyst for oxygen reduction catalysis, which exceeds the DOE 2020 technique target in both liquid half-cell and membrane electrode assembly conditions, representing a promising strategy to overcome this long-standing barrier
