Composite microtubes of Mo 2 C/MoCO have been synthesized for the first time under well‐controlled conditions by thermal decomposition of Mo(CO) 6 at about 600 °C. Here, thermal stability and phase transition of the products, as well as the influence of reaction temperature and argon flow rate, have been carefully investigated. All samples were characterized by X‐ray powder diffraction (XRD), scanning electron microscopy (SEM), and X‐ray photoelectron spectroscopy (XPS). The reaction model and rolling mechanism were proposed on the basis of the experimental facts.
