Manufacturing method of Te and bismuth telluride nano tubes by solvothermal synthesis

摘要

PURPOSE: A tellurium nanotube of solvothermal synthesis and a manufacturing method of bismuth telluride are provided to manufacture Te nano-tube by reacting a high-boiling point organic solvent, coupling agent, and Tellurium compound and to mass produce Bi2Te3 nano-tubes. CONSTITUTION: A tellurium nanotube of solvothermal synthesis comprises the following steps: manufacturing a mixed solution by mixing organic solvent with a coupling agent; and reacting tellurium compound in the mixture. The organic solvent is one or more kinds which are selected from ethylene glycol, oleic acid, oleylamine, hexadecane, ethylenediamine, dimethylformamide, pyridine, and acetone. The coupling agent is selected from polyviny pyrrolidone, polyvinylalcohol, cetyl-trimethyl-ammonium-bromide, ethylenediaminotetraacetic acid disodium salt, and sodium dodecyl-benzene-sulfonate. A manufacturing method of the Bi2Te3 nanotubes comprises a step of reacting a solution including bismuth compound and reducing agent with a solution which includes Te nano-tubes.
