Photoinduced water splitting in pyridine water clusters

N Esteves-López, S Coussan… - Physical Chemistry …, 2016 - pubs.rsc.org
Ab initio calculations predict that pyridine (Py) can act as a photo-catalyst to split water by
the absorption of a UV photon following the reaction Py–H2O+ hν→ PyH˙+ OH˙. To test this …
