Sacrificial acceptor

{
  "id": "MLC-T-CHM-010472",
  "term": "Sacrificial acceptor",
  "field": "Chemistry",
  "definition": "A molecular entity that takes up the electron in a photoinduced electron transfer and is then destroyed by an irreversible chemical reaction, so it is never regenerated. Its consumption blocks back electron transfer, letting the oxidized product of the partner accumulate. Persulfate, silver(I) and iodate are typical sacrificial acceptors in photocatalytic water oxidation to oxygen.",
