Synthesis and Characterization of Barium Sulfate Nanotubes

Tubular barium sulfate, having diameters in the range of 200–350 nm and length up to 30 microns, was fabricated by a nanochannel reactor and characterized by scanning electron microscope, transmission electron microscope, and X-ray diffractometer. The process is very simple, efficient and easy to control, which can be used to prepare a wide range of tubular inorganic nanomaterials.
