report a facile synthesis of carbon quantum dot (CQD)-sensitized
TiO2/Pt nanocomposites as efficient and robust photocatalysts
for light-driven proton reduction from water. We show that this method
not only simplifies the synthetic procedure for such hybrid materials
but also enhances the direct interaction between CQDs and TiO2, which facilitates charge transfer from CQDs to TiO2 and eventually improves its performance for light-driven H2 generation. To the best of our knowledge, this work represents the
system with highest H2 generation efficiency among all
CQD-sensitized materials.
