A Ti-supported NiCo2O4 nanosheet array exhibited high catalytic performance in the hydrolysis of ammonia borane for hydrogen generation.

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 H2 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.

The development of cost-effective and high-performance catalysts for the production of hydrogen via electrocatalytic water splitting is crucial for meeting the increasing energy demand and expanding the hydrogen economy. In...
