▎ 摘　　要

NOVELTY - Manufacturing hollow metal oxide nanotubes comprises preparing a precursor mixture solution by mixing carbon nanoparticles, a metal oxide precursor and a solvent, preparing a coating composite including a core and a shell by coating the surface of the carbon nanoparticle with the metal oxide precursor by irradiating the precursor mixture solution with ultrasonic waves, and calcining the coating composite to obtain metal oxide nanotube structure. USE - The hollow metal oxide nanotube is useful for producing carbon-coated metal oxide nanotube (claimed). ADVANTAGE - The hollow metal oxide nanotube has good conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for producing carbon-coated metal oxide nanotubes, comprising preparing the metal oxide nanotube structure, coating a carbon source solution on the metal oxide nanotube structure to obtain a coating structure, and calcining the coating structure under inert atmosphere.
