“…Owing to the complexity of many carbonaceous structures, the chemical shift ranges for various functional groups are not always clearly defined, and overlap is common. [105] However, complex carbonaceous structures can be analyzed in detail by combining data from multiple solid state NMR techniques.…”

“…An ordered mesoporous carbon was also functionalized with sulfonate groups by contacting the carbon with the vapor of fuming sulfuric acid inside an autoclave. [105] Under optimal conditions, a surface concentration of 1.3 mmol g À1 was achieved on this material, which served as an active and selective catalyst for several catalytic reactions, including rearrangement and condensation reactions.…”

Recent progress in syntheses of porous carbons with designed pore architecture has rejuvenated the field of carbon chemistry and promises to provide new advanced materials. In order to reap the full benefit of designer carbons, it is necessary to develop chemistries for functionalizing the porous carbon surfaces. This Review examines methods of functionalizing porous carbon through direct incorporation of heteroatoms in the carbon synthesis, surface oxidation and activation, halogenation, sulfonation, grafting, attachment of nanoparticles and surface coating with polymers. Methods of characterizing the functionalized carbon materials and applications that benefit from functionalized nanoporous carbons with designed architecture are also highlighted.

“…Sulfonated carbon materials, such as sulfonated hexagonal tube-like mesoporous carbon [23,26], sulfonated carbon nanotubes [34,35] and sulfonated amorphous carbon material [11] etc., have attracted considerable attention due to their applications in catalysis as Brønsted acid catalysts, and fuel cells [35]. We attempted to explore the functionalization of carbon nanocage CKT-3(A) with sulfophenyl group and its catalysis effect as solid Brønsted acid.…”

A carbon nanocage material (CKT) was first successfully sulfonated by introducing sulfophenyl groups on the surface of pore channels through benzenesulfonic acid-containing aryl radical in situ generated from the reaction of 4-aminobenzenesulfonic acid and isoamyl nitrite in water. The sulfonated carbon nanocage material (S-CKT) was characterized by Fourier transform infrared spectroscopy, transmission electron microscopy, powder small-angle X-ray diffraction and nitrogen sorption measurements. The results showed that the S-CKT still possess the high specific surface area (787 m 2 /g) and uniform mesoporous (pore diameter 4.7 nm) structures, although the structure of S-CKT is slightly disorder, compared with its unsulfonated precursor. S-CKT, as a carbon-based solid acid catalyst, showed good catalytic performance and reusability in the cross-Aldol condensation of ketones with aromatic aldehydes under solvent-free condition.

“…The sulfonation of MNPsSi-PPh 3 was completed by the method of vapour-phase sulfonation as described [16]. The sulfonation was performed in a Teflon-lined autoclave where MNPsSi-PPh 3 powders of 3 g were contacted with the vapor from 50 mL 50 wt% SO 3 /H 2 SO 4 at 353 K for 72 h. The sulfonated samples were washed with hot deionized water ([353 K) to remove any physically adsorbed species until the sulfate ions were not detected in the upper layer solution.…”

The facile two-step preparation procedure of a novel magnetic nano-solid acid catalyst is described, which includes grafting an ionic liquid onto Fe 3 O 4 nanoparticles, followed by the sulfonation of phenyl groups in the ionic liquid. The catalytic performance of this novel material has been systematically studied in the acetal formation of benzaldehyde and ethylene glycol. The experimental results testify this catalyst possesses high catalytic activity with a yield of 97% under mild reaction conditions. Furthermore, the catalyst is readily separated using a permanent magnet and it is reusable without any significant decrease in catalytic activity.
