We report new developments on the chemical vapor deposition growth of 0.4nm single-walled carbon nanotubes (SWCNTs) inside the linear channels of the aluminophosphate zeolite, AlPO4-5 (AFI), single crystals (0.4nm-SWCNT@AFI). Ethylene (C2H4) and carbon monoxide (CO) were used as the feedstock. Polarized Raman spectroscopy was used to analyze the structure and quality of SWCNTs, both the radial breathing...
Carbon membranes were prepared from a novel polymeric precursor of poly(phthalazinone ether sulfone ketone) (PPESK), of which the changes of microstructure and chemical compositions during pyrolysis from 500°C to 950°C were monitored by thermal gravimetric analysis, X-ray diffraction, X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy. It has been found that the weight loss...
A simple chemical vapor deposition method was used to prepare carbon spheres (CPS) from toluene without any catalysts. The diameters of CPS are in a range of 60 nm to 1 μm and can be controlled by changing the composition and flow rate of a mixture gas that was used as the carrier gas. The carbon spheres have been systematically studied by scanning electron microscopy (SEM), element analysis, energy...
