Abstract
A micro-nanotube of new inorganic compound with external shape of tetragonal prism has been synthesized. It is made of transitional metal oxychloride. From SEM detection, the micro-nanotube has an external diameter of 100-500 mn and an internal diameter of 60-300 nm. Its wall is very thin, 20-70 nm, and its length is from a dozen micro to dozens of microns (to see Fig. 1 (a-d) It has been prepared by solid state reaction in a direct growth way. From XRD, TEM and SEM determination, the micro-nanotube crystal belongs to orthorhombic system and its lattice constants are a=0. 5864(2)nm, b=0. 6032(2)nm and c=2. 972(2)nm(to see Fig. 1 similar to2 and Table 1). It possesses semiconducting properties. From curve log(1/p) similar to 1/T, its energy gap is E(g)approximate to1.2 eV(to see Fig. 3). The micro-nanotube material will be a prospect material used as catalysts, material to store gases or energy, and material used as electrode in photoelectric cell and photoelectrolytic cell. Additionally, the preparation of the micro-nanotube material by solid state reaction is simple in operation and cheap in cost.
