Visible‐Light‐Driven Photocatalytic Hydrogenation of Olefins Using Water as the H Source

Abstract

Abstract In this work, a highly efficient PCN‐KCl (KCl‐modified polymeric carbon nitride) nanosheet photocatalyst was synthesized with the assistance of KCl. The as‐prepared PCN‐KCl catalyst shows a more than 30‐fold enhancement in the photocatalytic activity for H 2 evolution from water compared to the pristine PCN. More importantly, when PCN‐KCl was composited with a second catalyst (Pd nanoparticles), the simultaneous production and utilization of active H species for alkenes hydrogenation was achieved by visible light irradiation under ambient conditions.
