The abundant-metal-based polyoxometalate complex Co (4) (H (2) O) (2) (PW (9) O (34) ) (2) (10-) is a hydrolytically and oxidatively stable, homogeneous, and efficient molecular catalyst for the visible-light-driven catalytic oxidation of water. Using a sacrificial electron acceptor and photosensitizer, it exhibits a high (30%) photon-to-O (2) yield and a large turnover number (>220, limited solely by depletion of the sacrificial electron acceptor) at pH 8. The photocatalytic performance of this catalyst is superior to that of the previously reported precious-metal-based polyoxometalate water oxidation catalyst Ru (4) O (4) (OH) (2) (H (2) O) (4) (γ-SiW (10) O (36) ) (2) (10-).
