Nitrogen-doped reduced graphene oxide supports for noble metal catalysts with greatly enhanced activity and stability

Selective oxidation of glycerol over nitrogen-doped carbon nanotubes supported platinum catalyst in base-free solution

“…1a, Fig. S2 and Table S2) [31,33]. These results indicated that N atoms were incorporated into carbon skeletal of N-MWCNTs, and the relative percentage of graphitic N increased from 5 to 16.7% when the calcination temperature was raised from 673 to 973 K because of the rearrangement of nitrogen groups under high temperature (Table S2) [34].…”

Effect of polymer modifier chain length on thermal conductive property of polyamide 6/graphene nanocomposites

“…4b and S1b) can also prove the structures of rGO and GP. The Raman spectrum of GO demonstrated a D band at 1339 cm −1 , corresponding to sp 3 -hybridized carbons and assigned to the breathing mode of κ-point phonons of A 1g symmetry; The G band at 1595 cm −1 corresponds to sp 2 -hybridized carbons and assigned to the first-order scattering of E 2g phonons [5,32,33]. The Raman spectra of the rGO also contained both D 11 and G bands (at 1326 and1577 cm −1 , respectively); however, rGA possessed a higher D/G intensity ratio [I(D/G)] than GO.…”

Understanding Heteroatom-Mediated Metal–Support Interactions in Functionalized Carbons: A Perspective Review

“…High metal dispersion was detected for different metal species (Au [92], Pd [93], Pt [94,95], Co [87], MoS2 [96]) on several doped carbon surfaces (N and O-doped carbon nanotubes, N-doped mesoporous carbon, N-doped carbon shells, carbon nanosphere, polyaniline (PANI) fibers). The presence of nitrogen has been demonstrated to assure excellent metal dispersion, even at very high metal loading [93].…”
