Synthesis of titanate, TiO2 (B), and anatase TiO2 nanofibers from
natural rutile sand
Abstract
Titanate nanofibers were synthesized by hydrothermal method (150 1C for 72 h) using natural rutile sand as the starting materials.
TiO2 (B) and anatase TiO2 (high crystallinity) nanofibers with the diameters of 20–100 nm and the lengths of 10–100 mm were
obtained by calcined titanate nanofibers for 4 h at 400 and 700 1C (in air), respectively. The samples characterized by XRD, SEM,
TEM, SAED, HRTEM, and BET surface area. This synthesis method provides a simple route to fabricate one-dimensional
nanostructured TiO2 from low cost material.
