Journal ArticleDOI
Visualization of cation diffusion at the TiO2 interface in dye sensitized photoelectrosynthesis cells (DSPEC)
Wenjing Song,Hanlin Luo,Kenneth Hanson,Javier J. Concepcion,M. Kyle Brennaman,Thomas J. Meyer +5 more
TL;DR: In this article, Li+ doping levels depend on the competition between dynamics of its intercalation and electron recombination/transport, which is screened by cation inter-calation.
Journal ArticleDOI
Multiple Pathways for Benzyl Alcohol Oxidation by RuV═O3+ and RuIV═O2+
Amit Paul,Jonathan F. Hull,Michael R. Norris,Zuofeng Chen,Daniel H. Ess,Javier J. Concepcion,Thomas J. Meyer +6 more
TL;DR: Significant rate enhancements are found for benzyl alcohol oxidation by the Ru(V)═O(3+) form of the water oxidation catalyst with added bases due to a new pathway, concerted hydride proton transfer (HPT).
Journal ArticleDOI
Chloride-assisted catalytic water oxidation
TL;DR: Observations based on the single-site catalyst suggest a mechanism involving initial oxidation of the catalyst to Ru(V)(O)(3+) followed by Cl(-) oxidation to HOCl, which is oxidized to O2.
Journal ArticleDOI
Mechanism of Catalytic Water Oxidation by the Ruthenium Blue Dimer Catalyst: Comparative Study in D2O versus H2O
TL;DR: Combined results under the conditions of these experiments at pH 1 indicate that oxidation of BD[3,4]′ is a rate limiting step in water oxidation with the BD catalyst.
Journal ArticleDOI
Vibrational and structural mapping of [Os(bpy)3]3+/2+ and [Os(phen)3]3+/2+
Konstantinos D. Demadis,Dana M. Dattelbaum,Edward M. Kober,Javier J. Concepcion,Jared J. Paul,Thomas J. Meyer,Peter S. White +6 more
TL;DR: In this article, structural changes between [OsIIL3]2+ and [Os IIIL3]3+ (L: 2,2′-bipyridine; 1,10-phenanthroline) and molecular and electronic structures of the OsIII complexes are discussed.
