摘要

A novel Cr ₂ O ₃ /TNTs nanocomposite was prepared by loaded suitable amount of amorphous Cr ₂ O ₃ on titanate nanotubes (TNTs) via hydrothermal reaction and impregnation process. XRD, SEM and TEM results demonstrated that the amorphous Cr ₂ O ₃ nanoparticles were homogeneously dispersed on the surface of TNTs. The diffuse reflectance UV-visible absorption spectra exhibited that the spectral response of TNTs was extended to visible light region by coupled with Cr ₂ O ₃ . The 2.5Cr ₂ O ₃ /TNTs nanocomposite showed the highest activity of hydrogen generation by photocatalytic water-splitting under visible light irradiation (λ > 400 nm). The high activity of H ₂ evolution for Cr ₂ O ₃ /TNTs nanocomposites was associated with the donor level in the forbidden band of TNTs semiconductor provided by dopant Cr ³⁺ and a probably photocatalytic mechanism was proposed.
