Carbon‐Catalyzed Oxidative Dehydrogenation of n‐Butane: Selective Site Formation during sp³‐to‐sp² Lattice Rearrangement

Nanodiamond decorated few-layer graphene composite as an efficient metal-free dehydrogenation catalyst for styrene production

“…before and after the catalytic reaction, which are exposed in the air before analysis the oxygen functionalities. High-resolution TEM analysis fully supports the results of TPO-MS and XPS, showing the formation of graphitic ribbons, onions-like carbon, and concentric graphitic shells in ND/FLG catalyst after DH reaction [13,33]. Fig.…”

“…NDs wrapped with graphene layer with an unique sp 2 -sp 3 hybrid structure, which provides high activity related to a partial delocalization of the electron density. The sp 2 -sp 3 hybrid structure of NDs also actively contributes to the reduction of coke formation on the carbon surface [13]. However, commercial NDs in a powder form are composed of agglomerates which significantly reduce the accessibility of the active sites.…”

Nitrogen‐Doped Annealed Nanodiamonds with Varied sp2/sp3 Ratio as Metal‐Free Electrocatalyst for the Oxygen Reduction Reaction

“…Such a special structure has a significant impact on the catalytic activity and stability, owing to the different roles of the diamond cores (sp 3 ) and the graphene envelopes (sp 2 ) in the ORR. [4] Moreover, as the catalyst of some gas phase reactions, AND has displayed excellent stability.…”

Phosphorous-modified ordered mesoporous carbon for catalytic dehydrogenation of propane to propylene

“…S. Su 18 stated that in general, the termination of carbon sheets always requires foreign atoms to saturate dangling bonds, and therefore, the intrinsic properties of carbon materials could be readily modified by the introduction of heteroatoms to functionalize graphene geometries at defects, edges or strained regions 19 . Many previous studies using carbon materials as catalysts doped with heteroatoms, such as P, B and N, to alter the performance of electrode materials, Fischer-Tropsch synthesis catalysts, and oxidative dehydrogenation catalysts [20][21][22] . In these cases, doped heteroatoms improved the properties of the carbon materials by changing electrical conductivity or oxidation reduction behavior of different functional groups.…”
