Preparation of One-Dimension Orthorhombic NaNbO₃ Long Rods by Combining Hydrothermal Method with Post-Heat Treatment

Abstract:

One-dimensional orthorhombic NaNbO₃ long rods were successfully prepared by combining a traditional hydrothermal method with the post-heat treatment. In the hydrothermal reaction process, sandia octahedral molecular sieves (SOMS) were synthesized at 160°C using Nb₂O₅ and NaOH as the initial reactants. Then, the effects of different post-heat treatment conditions on the morphology and crystallinity of product were investigated. Results showed that post-heat temperature could promote the crystal of the product to form orthorhombic NaNbO₃, and the axis of the long rod ran along the [001] direction of NaNbO₃ orthorhombic unit cell. Our study may provide a new approach for the preparation and investigation of one-dimensional alkali niobate photocatalytic materials and template grain for textured alkali niobium.
