“…However, deeper interpretation could be misleading because the CNTs do not present a 3D crystalline structure. Indeed, many groups already investigated disordered carbons by XRD [75][76][77]. They found that turbostratic carbon, which exhibits the same stacked graphene layers with a regular spacing as in graphite but different degree of stacking order, already shows a significantly different XRD pattern compared to hexagonal graphite.…”

For many years the scientific community has believed in a promising future for carbon nanotubes for various applications in such diverse fields as polymer reinforcement, adsorption, catalysis, electronics and medicine. Industrial production of carbon nanotubes and -fibers and the subsequent availability and decrease of price, have rendered this vision feasible. In the last years, several carbon nanomaterial products have been marketed by major chemical companies. In this work, we present an extensive characterization of a representative set of commercially available carbon nanomaterials. Special focus has been put on their quality, i.e. presence of metal or carbonaceous impurities but also homogeneity and structural integrity. The observations are of importance for subsequent use in catalysis where the presence of impurities or defects in the nanostructure can dramatically modify the activity of the catalytic material..

“…According to Quasipercolation model proposed by Andrew et al [41], the graphitic layer plane grows by carbon rings to nucleate and form the theoretical pore with the increasing carbonization temperature, so the theoretical pore size can be approximately calculated. Figure 6 shows the theoretical pore of PAN carbon membranes prepared in vacuum and Ar.…”

Effect of carbonization atmosphere on the structure changes of PAN carbon membranes

PAN carbon membranes were prepared by carbonizing the initial PAN membranes in vacuum and Ar at different temperatures. FTIR, Raman and XRD were applied to study the influence of carbonization atmosphere on the structure changes of PAN carbon membranes. The variations in adsorption peaks of FTIR, the intensity, position and FWHM of the Raman peaks, and microcrystallite parameters from XRD (e.g., d 002 , Lc and La) are correlated with the structure change of PAN carbon membranes. Analyses results reveal that vacuum atmosphere can produce PAN carbon membranes with higher order degree than those in Ar atmosphere, although the structures of PAN carbon membranes prepared in the two atmospheres are both amorphous. In addition, vacuum atmosphere can significantly accelerate the degradation reaction of PAN membranes and favors the preparation of carbon membranes with smaller pore size.
