In this review we discuss at the mechanistic level the different steps involved in water
oxidation catalysis with ruthenium-based molecular catalysts. We have chosen to focus on …

1. INTRODUCTION The design of organically modified surfaces is a rapidly expanding field
of research in materials science in which the central purpose is access to materials …

At the core of many important energy conversion processes in chemistry and biology are
oxidation-reduction reactions in which both electrons and protons are transferred. An …

The coupling between electron and proton transfers has a long experimental and theoretical
history in chemistry and biochemistry. To take just one example, the fact that acceptance of …

Degenerate hydrogen atom exchange reactions have been studied using calculations,
based on density functional theory (DFT), for (i) benzyl radical plus toluene,(ii) phenoxyl …

As the terminal step in photosystem II, and a potential half-reaction for artificial
photosynthesis, water oxidation (2H2O→ O2+ 4 e-+ 4H+) is key, but it imposes a significant …

The proton-coupled electron transfer (PCET) mechanism for the reaction Mox–OH+ e–+
H+→ Mred–OH2 was determined through the kinetic resolution of the independent electron …

Electrocatalytic water oxidation occurs through the use of the phosphonate-derivatized
single-site catalyst [Ru (Mebimpy)(4, 4′-((HO) 2OPCH2) 2bpy)(OH2)] 2+[Mebimpy= 2, 6-bis …

There is a remarkable redox chemistry of higher oxidation state M (IV)− M (VI) polypyridyl
complexes of Ru and Os. They are accessible by proton loss and formation of oxo or nitrido …

This review describes the work which has mainly been developed in our laboratory on
photoelectrochemical solar cells and on electrochemical devices in which suitable dyes are …
