Abstract

We report the development of a Z-scheme g-C₃N₄/Ag/AgI heterojunction by photo-deposition of Ag NPs on g-C₃N₄ and subsequent in situ generation of AgI via partial oxidation of Ag nanoparticles. A highly selective photoelectrochemical sensor for hydrogen sulfide (H₂S) detection was constructed based on a g-C₃N₄/Ag/AgI heterojunction and the transformation of the Z-scheme g-C₃N₄/Ag/AgI heterojunction to C₃N₄/Ag/Ag₂S.
