Ni3N-Scaffolded Amorphous Ni-Co-Mn Hydroxide/Oxyhydroxide Interfaces for Durable High-Current Alkaline Water Electrolysis.
Developing electrocatalysts that retain high activity under concentrated alkaline electrolyte, elevated temperature, and large current density remains challenging. Here, a hierarchical NiCoMn-NiN electrode was constructed by coupling a porous Ni3N framework with an amorphous Mn-containing Ni-Co hydroxide/oxyhydroxide-l...
