Key Points

Design an atomic-scale dual-site perovskite electrocatalyst to lower interfacial transport barriers and accelerate acidic hydrogen evolution through rapid hydrogen spillover.
Synthesized an orthorhombic SrHf1−xRuxO3−δ perovskite oxide featuring atomic-level Hf/Ru dual-metal catalytic pairs.
Assessed electrocatalytic hydrogen evolution reaction performance and kinetics under acidic conditions.
Investigated charge redistribution and the cooperative reaction mechanism across the Hf–O–Ru atomic bridge.
Demonstrated a three-step cooperative catalytic mechanism comprising proton adsorption on Hf sites, fast hydrogen migration via oxygen bridges, and H2 detachment from Ru sites.
Achieved enhanced specific acidic hydrogen evolution activity attributed to high conductivity and favorable charge redistribution within the Hf–O–Ru configuration.
