S-Scheme Homojunction Carbon Nitride for Photocatalytic Overall Water Splitting

Single semiconductor photocatalysts have disadvantages, such as low carrier separation efficiency. Although subsequent studies have effectively enhanced carrier separation by constructing heterojunction and other methods. However, due to the lattice mismatch, there is an increase in carrier complex sites at the interface between semiconductors, which hinders the further practical application of photocatalytic technology. To address the aforementioned challenges, in this study, carbon nitride nanotubes/carbon nitride nanosheets (TSCN) S-scheme homojunction with strong interfacial electric fields (IEF) and matched interfaces were constructed through an in situ one-step synthesis method. The carbon nitride…
