Efficient Light‐Driven Multi‐Electron Accumulation on Viologens by Molecular Control Over Photochemical Reaction Pathways

Chemistry – A European Journal, EarlyView.
Minimum structural changes, maximum output: By either utilizing a more oxidizing Ru(II) polypyridyl chromophore or by using a more reducing SED, the photocatalytic reduction of methyl viologen (MV2+) proceeds via a reductive quenching pathway. This not only significantly accelerates the overall photoreduction process but also allows accumulation of ...

A Low‐Oxidation‐State Mechanism for O─O Bond Formation in Photosystem II via Oxo–Hydroxyl Radical Coupling

Chemistry – A European Journal, EarlyView.
An oxo–hydroxyl radical coupling mechanism is identified for O─O bond formation in Photosystem II within the low‐oxidation‐state paradigm. Ca‐bound W3 forms Ox in the S4 state and subsequently couples with O5. The resulting hydroperoxide intermediate provides a mechanistic explanation for the poor resolution of Ox in XFEL structures.

Co‐Catalyst/Semiconductor Interface Coupling Design for Efficient Solar‐Driven Photocatalysis

EcoEnergy, EarlyView.
Interfacial coupling strength is proposed as a unifying descriptor governing charge‐transfer behavior in co‐catalyst/semiconductor photocatalytic systems. This review establishes a coupling‐strength‐guided framework that correlates interface engineering strategies with charge transport pathways, electronic structure regulation, and photocatalytic ...
