Efficient photocatalytic water oxidation catalyzed by polyoxometalate [Fe11(H2O)14(OH)2(W3O10)2-(α-SbW9O33)6]27- based on abundant metals

An eleven iron-containing nanoscale inorganic polyanionic oxide cluster was reported as the first example for exceptional photocatalytic water oxidation. Under optimal conditions, a remarkable turn-over number (TON) of 1815 +/- 50 and a turn-over frequency (TOFinitial) of 6.3 s(-1) over 1 were achieved for water oxidation.
