利用碳纳米管（CNTs）和二氧化钛（TiO 2）在强直流电脉冲作用下合成了单相层状碳化钛（TiC）。单相TiC层的制造被证实为从MWCNTs到多层石墨烯的转变。因此，其厚度和宽度几乎与转化的石墨烯层的厚度和宽度相同。这是首次报道单相层状纳米TiC的形成。采用扫描电子显微镜（SEM）、X射线衍射（XRD）、X射线光电子能谱（XPS）和高分辨透射电子显微镜（HR-TEM）对单相层状TiC结构进行了表征。
Single-phase layered titanium carbide (TiC) was successfully synthesized by reacting carbon nanotubes (CNTs) and titanium dioxide (TiO2) under a high direct current (DC) pulse. Single-phase TiC layer fabrication is confirmed as the transformation of multi-layered graphene from MWCNTs. Therefore its thickness and width is almost identical to those of transformed graphene layers. This is the first report on the formation of single-phase layered nano-TiC. Scanning electron microscopy (SEM), x-ray diffraction (XRD), x-ray photoelectron spectroscopy (XPS) and high-resolution transmission electron microscopy (HR-TEM) were used for the characteristic analysis of single-phase layered TiC structures.
