RuCo alloy trifunctional electrocatalysts with ratio-dependent activity for Zn–air batteries and self-powered water splitting

Herein, we reported a RuCo alloy with nitrogen-doped porous carbon (RuCo/NPC) as efficient trifunctional electrocatalysts for Zn-air batteries and water splitting. The versatility and catalytic activity of this catalyst is achieved by adjusting the Ru/Co ratio. The as-assembled Zn-air battery and overall water splitting with RuCo/NPC present outstanding catalytic performances.
