Increase and Enrichment of Active Electrons by Carbon Dots Induced to Improve TiO2 Photocatalytic Hydrogen Production Activity

Recombination of photogenerated carriers severely reduces the efficiency of photocatalytic reactions.Herein,Bio-CDs/TiO2 were produced using the hydrothermal method to tightly load biomass-based carbon dots(Bio-CDs)onto the surface of TiO2 via Ti-O-C bonds.Finite-difference time-domain(FDTD)simulations showed that the Bio-CDs act as electron storage pools in the Bio-CDs/TiO2,enhancing optical absorption and promoting the transfer and storage of photogenerate…查看全部>>
