Abstract
BaTi3O7·nH2O nanotubes have been synthesized through a hydrothermal reaction between Na-rich trititanate nanotubes and Ba(OH)2 within the pH range 12–8.2. These nanotubes possess the same layered crystal structure of the precursor Na2−xHxTi3O7·nH2O. They also keep the morphology of their precursor Na-trititanate nanotubes used in the synthesis, having an external diameter of 20–25 nm. The BaTi3O7·nH2O nanotubes remained fully stable up to 300 °C, while nanotubular form continues to exist up to 600 °C, together with amorphous particles.
