Undoped and vanadium (V)-doped titanium dioxide nanotubes (TNTs and VTNTs, respectively) were synthesized by hydrothermal method for biological applications. The fabricated nanotubes were characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), Raman spectroscopy, nitrogen adsorption-desorption isotherms, transmission electron microscopy (TEM), and scanning electron microscopy (SEM). The XRD and vibrational spectra results showed as-prepared nanotubes were complete anatase phase. The characterization of the morphology of the as-obtained nanotubes reveals that the samples are tubular in shape and the starting spherical titanium particles were fully transformed into a tubular material. The TEM and SEM results are in good agreement with XRD, FT-IR, and Raman analysis. The purpose of this study is to produce and characterize the vanadium-doped titanium dioxide nanotubes, such that this material can be employed for biomedical applications. TEM and SEM findings cleared that vanadium doping does not affect significantly the structure of titanium dioxide nanotubes which are uniform and compact.

钒掺杂二氧化钛纳米管的水热合成与表征

通过水热法合成了无掺杂和钒掺杂的二氧化钛纳米管(分别为TNT和VTNT),用于生物应用。通过X射线衍射(XRD),傅立叶变换红外光谱(FT-IR),拉曼光谱,氮吸附-解吸等温线,透射电子显微镜(TEM)和扫描电子显微镜(SEM)对所制备的纳米管进行表征。XRD和振动光谱结果表明,所制备的纳米管是完全的锐钛矿相。所获得的纳米管的形态特征表明,样品为管状,起始球形钛颗粒已完全转变为管状材料。TEM和SEM结果与XRD,FT-IR和拉曼分析非常吻合。这项研究的目的是生产和表征掺钒的二氧化钛纳米管,从而使该材料可用于生物医学应用。TEM和SEM结果表明,钒掺杂不会显着影响均匀且致密的二氧化钛纳米管的结构。
