Abstract

Ultrafine ternary carbide Co₆W₆C@C nanoparticles (NPs) were successfully synthesized and these NPs exhibited high catalytic activities for the hydrazine oxidation reaction (HzOR) under alkaline conditions. In a practical O₂–hydrazine fuel cell test, its peak power density reached 203 mW cm⁻², a value superior to that of the state-of-the-art commercial Pt/C catalyst.
