Electron Paramagnetic Resonance Characterization of Dioxygen-Bridged Cobalt Dimers with Relevance to Water Oxidation
Autor: R. David Britt, Troy A. Stich, J. Gregory McAlpin, Matthew L. Rigsby, Ryan M. Wall
Publikováno v: Inorganic Chemistry. 55:12728-12736
A variety of metal oxides can catalyze the oxidation of water to molecular oxygen when polarized by a sufficiently high electrochemical potential. Minimizing the overpotential and increasing the rate of the oxygen-evolving reaction (OER) are key goal

Comparison of cobalt and manganese in the chemistry of water oxidation
Autor: Troy A. Stich, William H. Casey, J. Gregory McAlpin, R. David Britt
Publikováno v: Coordination Chemistry Reviews. 256:2445-2452
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 b

Cooperation between bound waters and hydroxyls in controlling isotope-exchange rates
Autor: William H. Casey, C. André Ohlin, J. Gregory McAlpin, Shauna Christensen, Adele F. Panasci, R. David Britt, James R. Rustad, James C. Fettinger
Publikováno v: Geochimica et Cosmochimica Acta. 78:18-27
Mineral oxides differ from aqueous ions in that the bound water molecules are usually attached to different metal centers, or vicinal, and thus separated from one another. In contrast, for most mon ...

Polyoxometalate ions are used as ligands in water-oxidation processes related to solar energy production. An important step in these reactions is the association and dissociation of water from the catalytic sites, the rates of which are unknown. Here

Publikováno v: Chemistry (Weinheim an der Bergstrasse, Germany). 18(34)
Beneath the sheets: (31) P NMR data suggests that phosphates are liberated freely in the interlayer of a cobalt-hydroxide water-oxidation catalyst. The cobalt-hydroxide sheets are separated by an interlayer region with water, counterions and phosphat
