| Abstract: | The active sites of monodisperse transition metal Ni-clusters were anchored on carbon nitride (CN) by an in situ photoreduction deposition method to promote the efficient separation of photogener-ated charges and achieve high-efficiency photocatalytic activity for hydrogen evolution. The Ni-cluster/CN exhibited a photocatalytic hydrogen production rate of 16.5 mmol·h-1·g-1 and a total turnover frequency (TOF (H2)) value of 461.14 h-1. X-ray absorption spectroscopy based on syn-chrotron radiation indicated that CN had two reaction centers to form stable interface interactions with monodispersed Ni-clusters, in which carbon can act as an electron acceptor, while nitrogen can act as an electron donor. Meanwhile, the hybrid electronic structure of the Ni-cluster/CN system was constructed, which was favorable for photocatalytic activity for hydrogen production. An in-depth understanding of the interfacial interaction between CN and Ni-clusters will have im-portant reference significance on the mechanistic study of development based on the cocatalyst. |
