In this article, we reported a facile and effective strategy for assembling hybrid ZnAl-layered double hydroxide/carbon nanotubes (ZnAl-LDH/CNTs) nanocomposites through noncovalent bonds, for the first time, in the presence of L-cysteine molecules. The materials have been characterized by powder X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDS), transmission electron microscopy (TEM), thermogravimetry and differential scanning calorimetry (TG-DSC), X-ray photoelectron spectra (XPS) and specific surface area measurement. The results indicate that L-cysteine as bridging linker plays a key role for enhancing both adhesion and dispersion of LDH nanocrystallites onto the surface of CNTs matrix through the interfacial interaction, and effectively inhibits the in situ growth of LDH crystallites, thus resulting in remarkably reduced LDH crystallite sizes; the Eu(III) fluorescence quenching in intercalated-Eu(III)complex LDH/CNTs nanocomposite can occur because of the interaction between LDH crystallites and CNTs matrix. Furthermore, it is found that as-assembled hybrid LDH/CNTs nanocomposites exhibit excellent performance for photodegradation of methyl orange molecules under UV irradiation, which is closely related to the unique hybrid nanostructure and composition of composites.

A simple procedure is reported for the fabrication of TiO 2 nanofibers via electrospinning technique using polylactic acid (PLA), tetrabutyl titanate, and hexafluoroisopropanol as a spinning solution. TiO 2 nanofibers (600-700 nm in diameter), with bundled nanofibrils align in the fiber direction, are obtained from the calcination of the as-spun TiO 2 /PLA composite nanofibers at 550 C. The structure and physicochemical property of generated nanofibers are elucidated by Fourier transform-Infrared radiation spectrometer, X-ray diffraction, scanning electron microscope, and Thermogravimetric-differential thermal analysis, respectively. The photocatalytical activity of the TiO 2 nanofibers is testified by quantifying the degradation of methylene orange. The result indicates that the TiO 2 nanofibers with pure anatase phase, which are prepared at 550 C, shows an excellent photocatalytic activity.
