ABSTRACT A new method was developed for the synthesis of Cu2O-coated multi-walled carbon nanotubes (MWCNTs) on the basis of Fehling’s reaction. The method involved dispersion of carbon nanotubes in Fehling’s reagent, followed by addition of formaldehyde as a reducing agent. The Cu2O-coated MWCNTs were characterized by transmission electron microscopy, X-ray diffraction, X-ray photoelectron, Raman and UV–Vis spectroscopy, and superconducting quantum interference device measurements. These novel materials could be used in catalysis and optoelectronic applications.

    ABSTRACT: Nanocomposites composed of carbon nanotubes (CNTs) and magnetite (Fe3O4) nanoparticles were fabricated by using ethylene glycol as reductant at 160°C. The composites were subsequently annealed under different temperatures in an inert atmosphere. The products were characterized by transmission electron microscopy (TEM), high resolution TEM, X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. The results showed that the Fe3O4 transformed from amorphous phase into single crystalline nanoparticles after annealing and that the annealing temperature played a crucial role in controlling the size and the size distribution of Fe3O4 nanoparticles. The average size of Fe3O4 nanoparticles increased with increasing annealing temperature. Meanwhile, the size distribution of nanoparticles became wide with the increase of temperature. It was caused by the gradual decomposition of oleate groups attached on the CNT surface. Magnetic hysteresis loop measurements revealed that crystalline Fe3O4/CNTs displayed superparamagnetic behavior under room temperature.

    ABSTRACT: A hybrid nanostructure of multi-walled carbon nanotubes (CNTs) and β-ferric oxyhydroxide (β-FeOOH) nanoparticles is synthesized by ultrasonic-assisted in situ hydrolysis of the precursor ferric chloride and CNTs. Characterization by X-ray diffraction, scanning electron microscopy , and transmission electron microscopy establishes the nanohybrid structure of the synthesized sample. The results revealed that the surface of CNTs was uniformly assembled by numerous β-FeOOH nanoparticles and had an average diameter of 3 nm. The formation route of anchoring β-FeOOH nanoparticles onto CNTs was proposed as the intercalation and adsorption of iron ions onto the wall of CNTs, followed by the nucleation and growth of β-FeOOH nanoparticles. The values of remanent magnetization (M r) and coercivity (H c) of the as-synthesized CNTs/β-FeOOH nanocomposites were 0.1131 emu g, and 490.824 Oe, respectively. Furthermore, CNTs/β-FeOOH nanocomposites showed a very high adsorption capacity of Congo red and thus these nanocomposites can be used as good adsorbents and can be used for the removal of the dye of Congo red from the waste water system.

    ABSTRACT: In order to enhance the sensitivity of carbon nanotube based chemical sensors at room temperature operation, CNTs/CuO nanocomposite was prepared under hydrothermal reaction condition. The resulted-product was characterized with TEM (transmission electron microscopy), XRD (X-ray diffraction) and so on. A chemical prototype sensor was constructed based on CNTs/CuO nanocomposite and an interdigital electrode on flexible polymer substrate. The gas-sensing behavior of the sensor to some typical organic volatiles was investigated at room temperature operation. The results indicated that the carbon nanotube was dispersed well in CuO matrix, the CuO was uniformly coated on the surface of carbon nanotube, and the tubular structure of carbon nanotube was clearly observed. From morphology of TEM images, it can also be observed that a good interfacial adhesion between CNT and CuO matrix was formed, which maybe due to the results of strong interaction between CNTs with carboxyl groups and CuO containing some hydroxy groups. The CNTs/CuO nanocomposite showed dramatically enhanced sensitivity to some typical organic volatiles. This study would provide a simple, low-cost and general approach to functionalize the carbon nanotube. It is also in favor of developing chemical sensors with high sensitivity or catalysts with high activity to organic volatiles at low temperature.
