Beschreibung
Zusammenfassung:	PURPOSE: A manufacturing method of metal oxide nanofiber having hollow structure is provided to have stable hollow structure by plasticizing and coating metal precursor solution which has glycol solvent to the non-aqueous polymer nanofiber. CONSTITUTION: The manufacturing method of metal oxide nanofiber having hollow structure comprises the following steps. a) Non-aqueous polymer nanofiber is prepared through the electric radiation process. b) The precursor solution containing metal ion is prepared by melting the precursor containing metal ion in the Glycol. c) The non-aqueous polymer nanofiber is dipped in the precursor solution containing metal ion to be coated. d) Non-aqueous polymer is removed by firing the non-aqueous polymer nanofiber coated with the precursor solution which contains the metal ion.
