An original growth mode of MWCNTs on alumina supported iron catalysts
Abstract. Multi-walled carbon nanotubes (MWCNTs) have been produced from ethylene by fluidized bed-catalytic chemical vapor deposition (FB-CCVD) on alumina supported iron catalyst powders. Both catalysts and MWCNTs-catalyst composites have been characterized by XRD, SEM-EDX, TEM, Mössbauer spectroscopy, TGA and nitrogen adsorption measurements at different stages of the process. The fresh …

Structural and Magnetic Characterization of Co and Ni Silicate Hydroxides in …
X-ray diffraction, transmission electron microscopy, X-ray absorption spectroscopy, and magnetic measurements were used to investigate highly porous silica aerogels containing iron and cobalt or iron and nickel, calcined at 450 °C, which are intermediates in the formation of CoFe2O4-SiO2 and NiFe2O4-SiO2 aerogel nanocomposites. Aerogels without iron and pure Co and Ni silicate hydroxides w…
