NiMo bimetallic catalyst is synthesized by the simple solution combustion method, and high quality carbon nanotubes are synthesized by chemical vapor deposition(CVD) with CH4 as carbon source. The effects of catalyst composition, preparation temperature and CH4 flow rate on the preparation of carbon nanotubes by CVD are investigated, and the catalyst and carbon nanotubes are characterized by means of XRD, Raman, SEM, TEM, etc. In this experiment, the cutting-edge scientific research results are integrated into the experimental teaching, and the common knowledge about the synthesis and characterization of nano materials is introduced. In order to guide students to understand the effect of synthesis parameters on the growth of carbon nanotubes, the optimization of synthesis parameters of CVD carbon nanotubes is carried out, which is helpful to cultivate students’ scientific research thinking and stimulate their research interest.
