Summary: This study reports a heterogeneous electrocatalyst constructed by growing highly dispersed iron-rich bimetallic phosphide nanoparticles on metallic Ni3N, which exhibits outstanding bifunctional catalytic activities for alkaline seawater splitting. The optimal Fe0.74Co0.26P/Ni3N and Fe2P/Ni3N electrocatalysts demand only 113 and 212 mV for hydrogen and oxygen evolution reactions in 1 m KOH, respectively, substantially accelerating overall water/seawater electrolysis. Particularly, Fe2P/Ni3N shows an unprecedented overpotential of 302 mV at 500 mA cm(-2), surpassing most of the reported non-noble electrocatalysts. This work provides a new approach for developing high-performance electrocatalysts for seawater splitting.

Summary: This review focuses on the sluggish reaction kinetics at the oxygen cathode in metal-air batteries, which is a major obstacle to their commercialization. The use of noble-metal electrocatalysts has been a potential solution, but their high cost and scarcity hinder their widespread application. The review discusses the mechanisms of oxygen reduction reaction (ORR) and oxygen evolution reaction (OER), proposes principles for bifunctional electrocatalysts, and presents state-of-the-art catalysts based on carbon and transition-metal materials. Additionally, it explores self-supporting 3D noble-metal-free bifunctional ORR/OER catalysts and provides perspectives on the future development of bifunctional electrocatalysts.
