TL;DR: Extensive spectroscopic, electrochemical, and inhibition studies firmly indicate that [Co4(H2O)2(PW9O34)2]10– is stable under catalytic turnover conditions: Neither hydrated cobalt ions nor cobalt hydroxide/oxide particles form in situ.

TL;DR: This review addresses central issues in green energy generation, the challenges in water oxidation catalyst development, and the possible uses of polyoxometalates in greenEnergy science.

TL;DR: A combination of polyanion size and charge allows the Keggin-type polyoxometalate (POM), a catalyst for some air-based organic oxidations, to fit snuggly in the pores of MOF-199 (HKUST-1), a metal-organic framework (MOF) with the POM countercations residing in alternative pores results in a substantial synergistic stabilization of both the MOF and the Pom.

TL;DR: The photocatalytic performance of this catalyst is superior to that of the previously reported precious-metal-based polyoxometalate water oxidation catalyst.

TL;DR: A series of experiments for thorough examination of active species under catalytic conditions and apply them to Co4POM provide strong evidence that this POM anion functions as a molecular catalyst, not a precursor for CoOx, and document that catalytic O2 evolution by Co 4POM, Co(2+)(aq), and CoOx have different dependences on buffers, pH, and WOC concentration.
