Abstract

The invention discloses an undone nitrogen doped carbon nanotubes derivative with good electrochemical performance and a preparation method thereof. Undoing bamboo-like nitrogen doped multi-walled carbon nanotubes along the longitudinal direction is conducted through a solution chemical oxidation method, and the nitrogen doped carbon nanotubes derivative is obtained; through controlling the degree of undoing, caterpillar-shaped nitrogen doped graphene / carbon tube composite materials with heterojunction structures are obtained when undoing is conducted half and nitrogen doped graphene nanobelts are obtained when undoing is completed. The undone carbon nano tube is used for modifying a glassy carbon electrode. It is indicated by the test of electrochemical performance that the materials obtained from the undone nitrogen doped carbon nanotubes derivative with good electrochemical performance have the advantages that the specific surface area is high, more reaction active sites are achieved, and the electron transfer rate is higher, so that the wide application prospects in the field of electrochemistry, such as capacitors, lithium batteries, electro-catalysis, and electrochemical sensors are achieved.
