Other S-scheme photocatalysts

S-scheme heterojunction is widely utilized for designing efficient photocatalysts. S-scheme photocatalysts retain the powerful redox ability by consuming useless photogenerated carriers. The inclusivity of designing S-scheme heterojunction allows a variety of materials to construct S-scheme photocatalysts. In addition to CdS, TiO2, and g-C3N4, other semiconductors, such as spinel, Bi-based compounds, black phosphorus, ZnO, and organic semiconductors, can fabricate S-scheme photocatalysts. Benefiting from the strong redox capability and efficient carrier separation, S-scheme photocatalysts have attracted extensive attention. Given that the conventional-semiconductor-based S-scheme photocatalysts are exposited in the preceding chapters, this chapter mainly introduces other S-scheme photocatalysts, including spinel-based, Bi-based, black phosphorus-based, ZnO-based, and organic-based S-scheme photocatalysts, to promote the progress of S-scheme photocatalysts.
