Understanding the two-electron I3–/– shuttle in Z-scheme photocatalysis

Abstract: In Z-scheme photocatalytic water splitting, the triiodide/iodide (I^3–/I^–) redox couple serves as a two-electron shuttle to transfer electrons between two semiconductor photocatalysts. This article explains how I^3– is generated from I^– and reduced back to I^–, and why acidic conditions stabilize I^3– while basic conditions lead to iodate formatio…
