Abstract

Abstract:

Trititanate nanotubes were synthesized from rutile TiO₂ via hydrothermal process. The influences of process parameters such as stirring, acid leaching and calcination temperature on formation and structure of nanotubes were observed by TEM. The results show that continuous stirring could improve the directional growth of TiO₂ particles and formation of trititanate nanoflakes, and nanotubes are formed in the acid leaching process. It also reveals that 300℃ is the critical transformation temperature between nanotubes and long-stick crystalline column. The nanotubes synthesized under optimal condition are uniform and longer than 1μm, and the ratio of length to diameter is 125:1.

Key words: trititanate nanotube, preparation, TEM
