C nanotubes are synthesized by catalytic route on ceramic supports (Al2O3, MgO and CaO), usually utilized for polymer reinforcing/flame-retardancy, aiming at nanotube-based hybrid preparation. Chemical vapor deposition is carried out in i-C4H10+H2 atmosphere over 17 wt% Fe-catalysts upon different conditions. In order to clarify the influence of support material, calcination (450 degrees C or 750 degrees C) and reduction temperature (500 degrees C or 600 degrees C) of the catalysts, and synthesis temperature (600 degrees C or 700 degrees C), catalysts utilized and nanotubes obtained are systematically investigated by the use of several analysis techniques (electron microscopy, X-ray diffraction, thermo-gravimetry and Raman spectroscopy). The results obtained show that, in the considered range of variation, support material is the most influential parameter. The most catalytically active alumina supports allow achieving higher yields, but involve larger metallic inclusions and lower crystalline quality. Remaining supports behave oppositely. The reasons for such differences are discussed in the light of the current assessments on the nanotube growth and the results obtained are compared with those available in literature for similar catalysts.

This paper describes a simple and effective method for the fabrication of hematite (α-Fe2O3) nanochain networks (NCNs) by using carbon nanotubes as templates. The α-Fe2O3 nanochains are made of numerous α-Fe2O3 nanocrystals, which exhibit weak ferromagnetic behavior at room temperature while showing antiferromagnetic behavior at low temperatures below the Morin temperature (180K). Furthermore, the α-Fe2O3 NCNs generate superhydrophilic surface displaying the contact angle of water of 0°. Therefore, the α-Fe2O3 NCNs may be applied in nanomagnetic filters to capture magnetic and paramagnetic micro- and nanocontaminations to obtain high purity liquid.
