Potential‐Driven Dynamic Spring‐Effect of Pd─Cu Dual‐Atoms Empowered Stability and Activity for Electrocatalytic Reduction (Adv. Sci. 28/2025)

Spring-Effect of Pd─CuDual-Atoms The dynamic “spring-like” behavior of Pd─Cu dual atoms can be stretched and recovered with potential variation, which remarkably elevates the structural stability and catalytic activity of Cu atoms for electrocatalytic reduction of H2CrO4 in strong-acid electrolytes. The modulated electron-orbit coupling effect of inter-metals effectively prevents Cu single-atoms from aggregating as nanoparticles driven by applied potential.
