Pyrolytically grown arrays of highly aligned B{sub x}C{sub y}N{sub z} nanotubes
A pyrolysis route has been used to synthesize arrays of highly aligned B{sub x}C{sub y}N{sub z} nanotubes in bulk. The structure and composition of the product were characterized by scanning electron microscopy, high-resolution transmission electron microscopy, and electron energy-loss spectroscopy. The length and diameter of the nanotubes are quite uniform in a large area of the reaction zone. The sizes of the aligned B{sub x}C{sub y}N{sub z} nanotubes from the whole reaction zone are 10--30 {mu}m in length and 20--140 nm in diameter. The x/z ratio of B{sub x}C{sub y}N{sub z} nanotubes for most nanotubes is about 1:1. The x/y ratio of B{sub x}C{sub y}N{sub z} nanotubes is up to 0.6. Within one nanotube, the x/y ratio is usually heterogeneous. The growth mechanism is also discussed.
