Interfacial confinement of ultra-low Pt single atoms via Co–Pt–C/N electronic bridging for efficient hydrogen evolution

Key Points

• To explore the efficiency of hydrogen evolution reaction (HER) using interfacial confinement of platinum single atoms.
• Anchored platinum single atoms (1.35 wt%) at cobalt interfaces via Co–Pt–C/N bridging.
• Measured overpotentials in acidic and alkaline electrolytes.
• Achieved 8 mV overpotential in acidic electrolyte.
• Achieved 18 mV overpotential in alkaline electrolyte.
