Synthesis Li-doping Titanate Nanotube by Ion Exchange Method.

초록

Titanate Nanotube(TNT) were prepared by hydrothermal treatment with NaOH solution. TNT were synthesized with TiO2(P25, Degussa) in NaOH solution at 120 oC for 24 h. The obtained nanopowders were washed at reached pH1 by HCl for Na+ to H+ ion exchange. And then, partially Li+ ion exchange by hydrothermal treatment with LiOH solution. The characteristic of Li-doped TNT is X-ray diffraction, Transmission electron microscopy, ICP analysis. Improvement of Li+ ion exchange effect is measured by lithium battery cycler system.
