"Exploring High-Entropy Alloys: Revolutionizing Electrocatalysis Research"
A research team has developed a new platform to study and control the atomic-level structure of high-entropy alloys' surfaces, specifically focusing on platinum high-entropy alloys (Pt-HEAs). They found that Pt-HEAs outperformed platinum-cobalt alloys in the oxygen reduction reaction (ORR), indicating that the atomic arrangement and distribution of elements near the surface contribute to their excellent catalytic properties. The team believes that their findings have broad applicability and can be used to advance electrocatalysis and functional nanomaterials.
