Electronegativity-Driven Heterointerfaces for Water Electrolysis: Thermodynamic and Kinetic Insights into Built-In Charge Transfer.
Interfacial electronic modulation via heterostructure engineering puts forward a promising route toward effective water electrolysis. However, the mechanistic connection between atomic-scale interface design, thermodynamic stability, and device-level performance remains unresolved. Here, we report non-noble nickel-base...
