Coaxial wires coax energy from water

Journal Article · · Nature Catalysis

Inexpensive, earth-abundant photoabsorbers for solar water splitting have, so far, not demonstrated notable performance. Now, voltage gained from a coaxial heterojunction coupled with nanostructure-enhanced photocurrent results in Cu2O photocathodes demonstrating benchmark water-splitting performance.
