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.
采用直流脉冲高压技术，成功地将碳纳米管（MWCNTs）和二氧化钛（TiO2）转化为单相层状碳化钛（TiC）。单相 TiC 层的形成被确认为多层层状石墨烯从 MWCNTs 中的转变。因此，其厚度和宽度几乎与转变的石墨烯层相同。这是关于单相层状纳米 TiC 形成的首次报道。利用扫描电子显微镜（SEM）、X 射线衍射（XRD）、X 射线光电子能谱（XPS）和高分辨率透射电子显微镜（HR-TEM）对单相层状 TiC 结构进行了特征分析。
