One-dimensional porous antimonic functional carbon nanotube, and preparation method and application thereof

The invention belongs to the field of sodium ion battery materials, and discloses a one-dimensional porous antimonic functional carbon nanotube, and a preparation method and application thereof. The ruthenium-containing compound or monodisperse nano ruthenium is mixed with a carbon precursor polymer, a pyrolyzed polymer, and an organic solvent for stirring, ultrasonic treatment and uniform dispersion to obtain a precursor solution; the obtained precursor solution is performed with electrospun to obtain a nano-composite fiber; and the nano-composite fiber is pre-oxidized and carbonized in an inert atmosphere or a reducing atmosphere to obtain a one-dimensional porous antimonic functional carbon nanotube. The invention introduces a ruthenium nano material into a carbon nanotube, the obtainedcomposite material has a very high specific surface area, and highly crosslinked conductive network and porous structure, and the application as negative electrode material for a sodium ion battery has a high specific capaci
