Surface segregation is just like an invisible hand in bimetallic electrocatalysts, which has the potential to migrate atoms to the bimetallic nanoparticle surface. On page 3221, Z. J. Xu and co‐workers explain how the external conditions that influence the surface energy may induce variation in the surface composition. It is of profound importance to control and utilize this as a way to produce superior bimetallic electrocatalysts.
