Iron polypyridyl catalysts assembled on metal oxide semiconductors for photocatalytic hydrogen generation

Abstract

A series of Fe(III) complexes was recently reported that are active for photocatalytic hydrogen generation when paired with fluorescein and triethylamine. Herein we report an Fe(III) complex immobilized on TiO₂ and SrTiO₃ that is significantly more active than the homogeneous system, achieving up to 7800 turnovers in 31 hours.
