Atomically Correlated Phosphorus-Sulfur Sites in Carbon Nitride for Efficient Hydrogen Peroxide Production. [PDF]

Adv Sci (Weinh)
Atomically correlated phosphorus–sulphur sites are introduced into graphitic carbon nitride to regulate charge distribution, suppress localized trapping, and enhance oxygen activation. The resulting metal‐free photocatalyst selectively promotes the two‐electron oxygen reduction pathway, enabling efficient hydrogen peroxide production in pure water ...
