Abstract

The S-scheme is a trending heterojunction phenomenon for photocatalytic hydrogen evolution. It initiates photo-induced holes and electrons for surface reactions by minimizing charge carrier recombination across the interface. This chapter discusses the fundamentals of the S-scheme, including its principle, underlying mechanism, and emergence as an efficient charge transport pathway. Furthermore, it presents various types of S-scheme junctions and their classification based on the type of oxidation and reduction photocatalysts. First, we discussed various S-scheme validation strategies based on advanced characterization techniques and experimental evidence. Lastly, we summarized a comprehensive literature review and future aspects of the S-scheme heterojunctions.
