Fabricating the Robust g-C₃N₄ Nanosheets/Carbons/NiS Multiple Heterojunctions for Enhanced Photocatalytic H₂ Generation: An Insight into the Trifunctional Roles of Nanocarbons

In this work, robust nanocarbons, including graphite (G), carbon nanotube (CNT), reduced graphene oxide (rGO), carbon black (CB), and acetylene black (AB), have been successfully coupled into the interfaces between g-C3N4 and NiS using a facile precipitation method. The results demonstrated that nanocarbons played trifunctional roles in boosting the photocatalytic H2 evolution over g-C3N4, which can not only act as effective H2-evolution...
