Bacteria-Triggered Solar Hydrogen Production via Platinum(II)-Tethered Chalcogenoviologens

Angew Chem Int Ed Engl. 2022 Mar 7;61(11):e202115298. doi: 10.1002/anie.202115298. Epub 2022 Jan 24.

Abstract

Multifunctional solar energy conversion offers a feasible strategy to solve energy, environmental and water crises. Herein, a series of platinum(II)-tethered chalcogenoviologens (PtL+ -EV2+ , E=S, Se, Te) is reported, which integrate the functions of photosensitizer, electron mediator and catalyst. PtL+ -EV2+ (particularly for PtL+ -SeV2+ )-based one-component solar H2 production could be triggered not only by EDTA, but also by facultative anaerobic and aerobic bacteria relying on a simplified mechanism, along with efficient antibacterial activities. In addition, by using real pool water, PtL+ -SeV2+ achieved multiple functions, including H2 production, antibacterial action and acid removal, which supplied a new strategy to solve various problems in real life via a single system.

Keywords: Antibacterial; Chalcogenoviologens; Solar H2 Production; Tripyridine-PtII Complex.
