Figure 5. (A) Time-dependent H₂O₂ yields over ZIS, BS and BZIS heterojunctions; (B) Comparison of the H₂O₂ production performance of BZIS-1/20 in pure water with other reported photocatalysts; (C) Cycling performance of BZIS-1/20 for H₂O₂ production; (D) H₂O₂ yields of BZIS-1/20 under different atmospheres; and (E) H₂O₂ yields of BZIS-1/20 in the presence of different scavengers. ZIS: ZnIn₂S₄; BS: Bi₂S₃; BZIS: Bi₂S₃/ZnIn₂S₄.
