Abstract:

Exploring low-cost cocatalyst to take over noble metal cocatalyst is still challenging in the field of photocatalytic proton reduction. Herein, Ni-P alloy clusters are anchored onto the surface of polymeric carbon nitride through a chemical plating method and serve as highly efficient and stable cocatalyst toward photocatalytic proton reduction. An effective role in promoting the charge separation and migration of the photocatalytic system is demonstrated for Ni-P clusters, which essentially enhance the photocatalytic H2-production rate to a value of 1506 μmol h-1 g-1. This performance is comparable to that of the benchmark of Pt-modified carbon nitride. This work highlights that the Ni-P alloy could be a potential alternative to noble metal cocatalyst in the photocatalytic reactions.
