The study investigates the visible light driven water oxidation reaction using the organic electron acceptor TCNQF(4) without any metal or organometallic catalysts. The generated oxygen and protons were measured to monitor the reaction efficiency. This work opens new perspectives for water photo-oxidation in liquids and artificial photosynthesis.
The visible light driven water oxidation reaction (WOR) by the organic electron acceptor 2,3,5,6-tetrafluoro-7,7,8,8-tetracyano-quinodimethane (TCNQF(4)) was studied at the water|butyronitrile interface. The WOR was performed at neutral pH, and without any metal or organometallic catalysts. The oxygen generated was measured by GC-MS and cyclic voltammetry, and the protons produced were monitored by measuring the aqueous pH. This work opens novel perspectives for water photo-oxidation in liquids and artificial photosynthesis.
