Abstract

The invention belongs to the technical field of isotope labeling, provides a 13C labeled carbon nanotube and a preparation method thereof, and solves the problem of difficult tracing of carbon nanotubes. The method comprises the following steps: mixing 13C powder, graphite powder and a catalyst under protective gas, and discharging to obtain carbon ash; and sequentially refluxing, dissolving and filtering the carbon ash to obtain the 13C-labeled carbon nanotube. According to the invention, the carbon nanotube is prepared from a solid material, the labeled carbon nanotube of stable isotope 13C substitution skeleton atoms is obtained through an arc discharge method, the method is comprehensive and efficient, and the original morphological structure and performance of the carbon nanotube can be retained. 13C is randomly distributed on the skeleton of the carbon nano tube, so that the reaction change of the carbon nano tube in an organism is effectively traced. The preparation method provided by the invention is simple and low in cost, and brings a new direction for in-vivo tracing of the carbon nanotube.
