Photocatalytic water splitting by 2D polymer with out-of-plane carrier flow

TL;DR - Researchers engineered 2D polymeric carbon nitride photocatalysts to drive charge carriers out of plane, improving overall water-splitting efficiency.

• Facet-selective nanofilms create internal electric fields within the polymer photocatalyst.
• These fields promote out-of-plane carrier migration, improving charge transport.
• The strategy increases the apparent quantum efficiency of photocatalytic water splitting.
