Titanate nanotubes were prepared via a hydrothermal treatment of TiO2 powders in a 10 M NaOH solution at 110–270 oC for 24 h. Effects of synthetic temperature on the morphology, phase structure, and pore structure of titanate nanotubes were characterized with TEM, XRD, and nitrogen isotherms, respectively. The adsorption capacity of two basic dyes, Basic Green 5 (BG5) and Basic Violet 10 (BV10), was then measured to identify how the changes of the microstructure affected the basic dyes adsorption characteristics of titanate nanotubes. It was found that when the synthetic temperature was above 160 oC, the microstructure of titanate may transformed from nanotube into nanorod accompanying with the sharp decrease of titanate interlayer spacing, BET surface area, and pore volume. The effects of pore structure variation on the basic dyes adsorption of titanate nanotubes were also discussed.
