✦ Synopsis

Eosin Y-sensitized TS-1 zeolite was studied for the photo-reduction of water into hydrogen driven by visible light (l ! 420 nm). The optimal pH and weight ratio between Eosin Y and TS-1 zeolite is 7 and 1/8, respectively. In the presence of triethanolamine (TEA) as an electron donor, the highest rate of hydrogen generation and apparent quantum efficiency are 34 mmol h À1 and 9.4%, respectively, under visible light irradiation (l ! 420 nm). Short-term stability test indicates that the catalyst is rather stable during 50 h photoreaction.
