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

Catalysis by hybrid sp2/sp3nanodiamonds and their role in the design of advanced nanocarbon materials

“…145 Similar results for the DH reaction of EB were reported by Pham-Huu's group. 146 Zhao and co-workers used instead a N-doped mesoporous graphene as a scaffold to obtain a ND/nitrogen-doped mesoporous graphene hybrid which displayed an improved activity. A synergy between graphene and NDs in the unique mesoporous nanoarchitecture was responsible for the enhanced reaction performance.…”

Nanodiamonds: Synthesis and Application in Sensing, Catalysis, and the Possible Connection with Some Processes Occurring in Space

“…However, the NDs employed were powders from detonation synthesis, which are of limited industrial interest due to incompatibility with fixed-bed configurations. Steps towards solving this issue by immobilizing NDs were taken by using a SiC foam [118] or few-layered graphene [119] as the supporting material.…”

Activity studies of vanadium, iron, carbon and mixed oxides based catalysts for the oxidative dehydrogenation of ethylbenzene to styrene: a review

“…Thus, carbon has emerged as an important metal-free catalyst for multiple types of heterogeneous catalysis mainly due to the active surface oxygenated groups. [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] On the other hand, the reaction over transition metals as well as metal oxide-based systems have also been investigated. Typically, the catalyst systems with vanadium [31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47] and iron [48][49][50][51][52][53][54][55][56][57][58][59][60][61][62] have been widely studied for the oxidative d...…”

“…47,64,69,79,80 A lot of studies on the catalytic performance of nanodiamond (ND) have been carried out for the direct dehydrogenation of ethylbenzene to styrene and it exhibited appreciable catalytic stability and selectivity. 20,24,25 Kotarba et al synthesized a composite ferrite catalyst comprising well-developed hexagonal nanoplates of K 2 Fe 22 O 34 . 56,81 Along with this, studies on nanocasted binary and ternary oxide (CeFe, SnFe, MnFe, CeFeZr, CeFeNi, and CeNiAl) composite catalysts have also been carried out for the oxidative dehydrogenation of ethylbenzene.…”
