Photoreduction

  "id": "MLC-T-CHM-008918",
  "term": "Photoreduction",
  "field": "Chemistry",
  "definition": "A reduction brought about by light, in which either a photoexcited species gains electrons or hydrogen atoms, as when excited benzophenone abstracts hydrogen from a donor to give a ketyl radical, or a photoexcited donor passes an electron to a ground-state substrate, which is then reduced. The counterpart reaction in the same system is an oxidation of the donor, so photoreduction and photooxidation often occur together.",
