Abstract:
Titanate nanotubes and nanofibers were synthesized by hydrothermal method using various alkaline solutions (NaOH and KOH) in order to study the effect of synthesis condition for hydrogen storage. The microstructures of titanate nanotube and nanofibers were characterized by XRD, TEM, FE-SEM. It was found that interlayer spacing of titanate nanotubes and nanofibers depended on the alkaline solution, because some of the Ti-O-Ti bonds were broken and layered titanate nanosheet of Ti-O-A (Na+ and K+) bonds were formed. The sorption of hydrogen of the titanate nanotubes and nanofibers were studied by the conventional volumetric pressure-composition isothermal method at RT, 30 atm. The relationships between interlayer spacing, ionic radius of alkaline solution and hydrogen capacity have been discussed.
