Embodiment 1
[0025] (1) Weigh 0.3g TiO 2 Powder and 4g NaOH, add water to prepare 25mL of suspension, place in a polytetrafluoroethylene reactor, react at 180°C for 12 hours, wash with deionized water and dry at 60°C for 24 hours to obtain Na 2 Ti 3 o 7 2H 2 O nanoribbons.
[0026] (2) Weigh the above-mentioned Na of 20mg 2 Ti 3 o 7 2H 2 O nanobelts were placed in a 15mL glass vial, and 10mL of hexane was added in the glove box to make Na 2 Ti 3 o 7 2H 2 After O nanobelts are dispersed inside, add 1mL butyllithium hexane solution (volume fraction 15%), let it stand after ultrasonication for 1 hour, and add enough ethanol to consume unreacted butyllithium, wash with ethanol and remove Wash with deionized water, and dry in an oven at 40-80°C for 12 hours to obtain Na 2 Ti 3 o 7 ·xH 2 O nanotubes.
[0027] Na obtained above 2 Ti 3 o 7 ·xH 2 O nanotube powders were tested by scanning electron microscopy, such as figure 1 As shown, the prepared Na 2 Ti 3 o 7 ·xH 2 O has...
