NiMoFe/Cu nanowire core–shell catalysts for high-performance overall water splitting in neutral electrolytes.

A bifunctional NiMoFe/Cu NW core–shell catalyst assembled into a practical solar-driven overall water splitting system leads to an unprecedented solar-to-hydrogen (STH) efficiency of 10.99% in neutral electrolytes, attributed to the synergic combination of a unique 3D self-supported core–shell architecture and rapid electron/mass transfer properties.
