Abstract

The electronic and optical properties are studied using the density functional theory in (Si,Fe)-codoped anatase TiO ₂ . The calculated results suggest that the synergistic effects of (Si,Fe) codoping can effectively induce the redshift of optical absorption edge, which leads to higher visible-light photocatalytic activity for hydrogen production by water splitting than pure anatase TiO ₂ . To verify the reliability of our calculated results, nanocrystalline (Si,Fe)-codoped TiO ₂ is synthesized by a sol-gel-solvothermal method, and excellent absorption performance and photocatalytic activity for hydrogen production by water splitting are observed in our experiments.
