Journal ArticleDOI
Application of the rotating ring-disc-electrode technique to water oxidation by surface-bound molecular catalysts.
TL;DR: With this technique, this work has been able to reliably obtain turnover frequencies, overpotentials, Faradaic conversion efficiencies, and mechanistic information from single samples of surface-bound metal complex catalysts.
Journal ArticleDOI
Interfacial dynamics and solar fuel formation in dye-sensitized photoelectrosynthesis cells.
Wenjing Song,Zuofeng Chen,Christopher R. K. Glasson,Kenneth Hanson,Hanlin Luo,Michael R. Norris,Dennis L. Ashford,Javier J. Concepcion,M. Kyle Brennaman,Thomas J. Meyer +9 more
TL;DR: Progress has been made on catalysts for water oxidation and CO(2) reduction, dynamics of electron injection, back electron transfer, and photostability under conditions appropriate for water splitting, and details are emerging which define kinetic and thermodynamic requirements for the individual processes underlying DSPEC performance.
Journal ArticleDOI
Structural and pH dependence of excited state PCET reactions involving reductive quenching of the MLCT excited state of [RuII(bpy)2(bpz)]2+ by hydroquinones.
Natalia V. Lebedeva,Robert D. Schmidt,Javier J. Concepcion,M. Kyle Brennaman,Ian N. Stanton,Michael J. Therien,Thomas J. Meyer,Malcolm D. E. Forbes +7 more
TL;DR: An observed equilibrium deuterium isotope effect supports the conclusion that the post-PCET HQ(•)/Q(•-) equilibrium is the most important in determining the 4a/4b ratio at early delay times.
Journal ArticleDOI
Synthesis and electrocatalytic water oxidation by electrode-bound helical peptide chromophore-catalyst assemblies.
Derek M. Ryan,Michael K. Coggins,Javier J. Concepcion,Dennis L. Ashford,Zhen Fang,Leila Alibabaei,Da Ma,Thomas J. Meyer,Marcey L. Waters +8 more
TL;DR: This approach combines solid-phase peptide synthesis for systematic variation of the backbone, copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) as an orthogonal approach to install the chromophore, and assembly of the water-oxidation catalyst in the final step, where the catalyst was found to be incompatible with the conditions both for amide bond formation and for the CuAAC reaction.
Journal ArticleDOI
Self-assembled bilayers on indium-tin oxide (SAB-ITO) electrodes: A design for chromophore-catalyst photoanodes
Christopher R. K. Glasson,Wenjing Song,Dennis L. Ashford,Aaron K. Vannucci,Zuofeng Chen,Javier J. Concepcion,Patrick L. Holland,Thomas J. Meyer +7 more
TL;DR: A novel approach for creating assemblies on metal oxide surfaces via the addition of a catalyst overlayer on a chomophore monolayer derivatized surface is described.
