A helical carbon nanotube anode with controllable pitch, a preparation method and application thereof

Abstract

The application provides a helical carbon nanotube anode with controllable pitch, a preparation method and application, and belongs to the field of preparation of microbial fuel cell anodes. The method is as follows: ZIF-67@CC is prepared first; the ZIF-67@CC is put into a prepared FeSO4 solution to react, and FeCo@CC is obtained; a double-temperature-zone tube furnace is used for CVD operation, melamine is put into the left temperature zone of the tube furnace, melamine is added into the right temperature zone of the tube furnace, then the FeCo@CC is put on the right temperature zone of the tube furnace, and the reaction is carried out under the protection of N2, and a helical carbon nanotube anode with controllable pitch is obtained. The application also provides the helical carbon nanotube anode with controllable pitch obtained by the above preparation method. The application also provides application of the helical carbon nanotube anode with controllable pitch in a microbial fuel cell. The application uses a solid carbon source, does not need to introduce other flammable and explosive gases such as ethyne, and the helical structure is controllable.
