    摘要
  • 摘要: 采用TiCl4水解法对表面酸功能化的碳纳米管（CNTs）进行TiO2涂层，然后通过程序升温还原(TPR)，使TiO2涂层转变为Ti涂层。利用SEM、TEM、XRD和EDAX对CNTs、CNT/TiO2 纳米复合材料和Ti 涂层CNTs进行表征。结果表明：超声波酸功能化CNTs后，可将TiO2成功地涂覆于CNTs表面；在850℃下、H2/Ar氛围中，通过TPR可将TiO2涂层还原为金属Ti涂层。该Ti涂层对CNTs和其他金属形成复合材料非常重要。
    Abstract: The surfaces of acid-functionalized carbon nanotubes (CNTs) were coated by TiO2 produced by the hydrolysis of TiCl4, which was converted into Ti through temperature-programmed reduction (TPR) equipment. SEM, TEM, XRD, and EDAX analyses were used to characterize the primary CNTs, as-prepared TiO2-coated CNTs and the Ti-coated CNTs. It was found that after the functionalization of CNTs by ultrasonic-assisted acid treatment, TiO2 was successfully coated onto the CNTs, which was reduced in TPR under H2/Ar flow at 850℃ to metal Ti. The Ti transition layer is important for the formation of composites of CNTs with other metals.
