Abstract  Transition element (Mn, Cr, Cu) substituted titanate nanotubes were fabricated by a simple method, i.e., hydrothermal method. The precursors used were Mn, Cr and Cu doped anatase TiO2 nanopowders, which were 20~30 nm in diameter. The obtained samples were characterized by SEM, TEM, XRD, EDX, PL and Raman spectra. The results show that the fluorescence-emission intensity of the substituted titanate nanotubes decreases to some extent with the substitution of metal ions. It is generally considered that the low recombination efficiency of the electron-holes means the high quantum efficiency of the photons. So the results show that the transition element substituted titanate nanotubes might be applied in the photocatalysis.
