| Abstract: | Water into oxygen: Mono-iridium complexes (see picture; L=PO(3) H(2) or COOH) were immobilized on an indium tin oxide (ITO) surface to form a molecular electrocatalytic water oxidation assembly that mimics photosystem?II in producing molecular oxygen with high turnover numbers (TONs). The catalyst shows TONs for O(2) higher than 210?000 and turnover frequencies higher than 6.7?s(-1) during electrochemical catalytic water splitting. |
