Özet

New photocatalytic systems for hydrogen evolution from water have been reported by using low cost and environmentally-friendly Cu2ZnSnS4, Cu2ZnSnSe4, and Cu2ZnSnSe4-xSx nanofiber catalysts in the presence of eosin Y as a photosensitizer and a sacrificial reducing agent triethanolamine under visible light irradiation. The rate of hydrogen evolution with Cu2ZnSnS4 is greater than those with Cu2ZnSnSe4 and Cu2ZnSnSe4-xSx, producing hydrogen at 1428 μmol g-1 h-1, 833 μmol g-1 h-1 and 739 μmol g-1 h-1, respectively.
