“…In addition, to replace the expensive Pt cocatalyst, a few other potential candidates, such as Au, 10 Ag, 11 black phosphorus, 12 and MoS 2, 13–24 and so on, have been incorporated with carbon nitride to form heterostructures for photocatalytic hydrogen production. Among them, MoS 2 is considered a promising alternative due to its low cost, abundance, and efficient catalyst for photocatalytic and electrochemical hydrogen evolution both under acidic and basic environments 21,25–27 . However, different from constructing heterostructures with metallic materials, building MoS 2 −carbon nitride heterostructure is quite complicated due to the semiconductor nature of MoS 2 .…”
