In this paper, carbon fibers with large diameter were successfully obtained by chemical vapour deposition CVD using copper tartrate as a catalyst precursor, which provided a new method to prepare carbon fibers with large diameter using nano catalyst directly. In addition, the paper investigated and proposed the growth mechanism of carbon fibers after analysis and observation of SEM and TEM photos of the product. The product in the experiment was characterized by field emission scanning electron microscopy FESEM, transmission electron microscopy TEM and X-ray powder diffraction XRD.
