Understanding polyoxometalates as water oxidation catalysts through iron vs. cobalt reactivity.

ABSTRACT: Cobalt polyoxometalates (Co-POMs) have emerged as promising water oxidation catalysts (WOCs), with the added advantage of their molecular nature despite being metal oxide fragments. In comparison with metal oxides, that do not offer well-defined active surfaces, POMs have a controlled, discrete structure that allows for precise correlations between experiment and computational analyses. Thus, beyond highly active WOCs, POMs are also model systems to gain deeper mechanistic understanding on the oxygen evolution reaction (OER). The tetracobalt Weakley sandwich [Co^II ₄(H₂O)₂(B-α-PW₉O₃₄)₂]^10- (Co4-WS) has been one of the most extensively studied. We have compared its activity with that of the iron an
