Recently, Nocera and coworkers claim that an artificial leaf - able to harvest up to 4.7% of incident photonic energy to split water and produce fuels using only Earth abundant elements - has been produced with much of its design inspired by photosynthetic elements [1]. In this short review, we compare the structure and function of the cobalt-based water oxidation center of the artificial leaf with what is known about the manganese-based oxygen-evolving complex (OEC) of photosystem II (PSII). The geometric structure, proposed oxidation state topology, and putative mechanism of water oxidation for the respective catalytic sites are discussed. (C) 2012 Elsevier B.V. All rights reserved.
