TL;DR: Electrochemical, kinetic, UV-vis, SEM, EDX, and other data provide four main lines of compelling evidence that, under the conditions used herein, the dominant WOC is actually heterogeneous CoO(x) and not homogeneous [Co(4)(H(2)O)(2)(PW(9)O(34))(2)](10-).
Abstract: The question of “what is the true catalyst?” when beginning with the cobalt polyoxometalate (POM) [Co4(H2O)2(PW9O34)2]10– in electrochemical water oxidation catalysis is examined in pH 8.0 sodium phosphate buffer at a glassy carbon electrode. Is [Co4(H2O)2(PW9O34)2]10– a true water oxidation catalyst (WOC), or just a precatalyst? Electrochemical, kinetic, UV–vis, SEM, EDX, and other data provide four main lines of compelling evidence that, under the conditions used herein, the dominant WOC is actually heterogeneous CoOx and not homogeneous [Co4(H2O)2(PW9O34)2]10–.

TL;DR: The cooperative assembly of Tris functionalized three-connected building blocks and rigid 1,3,5-benzenetricarboxylate gave rise to an unprecedented cubic polyoxometalate-organic molecular cage with high thermal and hydrothermal stability.
Abstract: Tris(hydroxymethyl)aminomethane (Tris) was successfully grafted onto the surface of a Ni6-substituted polyoxotungstate formed in situ to further generate a three-connected polyoxometalate building block. The cooperative assembly of Tris functionalized three-connected building blocks and rigid 1,3,5-benzenetricarboxylate gave rise to an unprecedented cubic polyoxometalate−organic molecular cage with high thermal and hydrothermal stability.
