Effective hydrothermal grafting of Eosin Y onto TiO2 nanoparticles towards stable photocatalysts for efficient visible-light-driven photocatalytic H2 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 H2 evolution activity under visible light (520 nm), achieving a 2.2 times higher turnover number for H2 evolution versus dye than the physical mixture of EY and TiO2 (EY-TiO2-mix).

Highly active dye-sensitized photocatalytic H2 evolution catalyzed by a single-atom Pt cocatalyst anchored onto g-C3N4 nanosheets under long-wavelength visible light irradiation

Herein, we report a highly active and durable single-atom Pt cocatalyst anchored onto g-C3N4 nanosheets (Pt–CN) for long-wavelength visible-light-driven photocatalytic H2 evolution. Upon spectral sensitization with Eosin Y (EY) dye, Pt–CN exhibits a ∼5-fold increase in specific activity over the Pt nanoparticles loaded g-C3N4 (Pt NPs–CN) under 520 nm irradiation and shows excellent recycling stability.
