Carbon quantum dots modified P25 TiO₂ composites (CQDs/P25) with a “dyade”-like structure were prepared via a facile one-step hydrothermal reaction. CQDs/P25 exhibited improved photocatalytic H₂ evolution under UV-Vis and visible light (λ > 450 nm) irradiation without loading any noble metal coca...
