Effective Hydrothermal Grafting Of Eosin Y Onto Tio2 Nanoparticles Towards Stable Photocatalysts For Efficient Visible-Light-Driven Photocatalytic H-2 Evolution

Herein, we report a simple hydrothermal method for effectively grafting the Eosin Y (EY) dye onto TiO2 nanoparticles to afford a stable EY-sensitized TiO2 photocatalyst (EY-TiO2-HT), which shows an improved and stable H-2 evolution activity under visible light (520 nm), achieving a 2.2 times higher turnover number for H-2 evolution versus dye than the physical mixture of EY and TiO2 (EY-TiO2-mix).
