Supported (NiMo,CoMo)-carbide, -nitride phases: Effect of atomic ratios and phosphorus concentration on the HDS of thiophene and dibenzothiophene

An efficient CoMoS2 nanosheets on nitrogen, sulfur dual doped reduced graphene oxide as an electrocatalyst for the hydrogen evolution reaction

“…8,14 The optimum metal content(Co/Co + Mo) 0.3 is achieved in Co 0.5 MoS 2 which showed better catalytic activity compared to the metal content 0.5 in CoMoS 2 catalyst, which is following previous reports. [48][49][50] This atomic ratio of 0.3, results in high promotion degree in Mo by Co as reported by Escobar. 51 It can be further explained that Co-Mo co-ordination reaches the highest in the ratio(0.5:1) and subsequently decreases with increasing Co which is due to the increased Co-S coordination hindering Co-Mo co-ordination which is the active site in Co-MoS 2 .…”

Development of nickel based catalysts for the transformation of natural triglycerides and related compounds into green diesel: a critical review

“…Their high intrinsic activity is due to the introduction of nitrogen, carbon or phosphorus into the lattice of the metal resulting to an increase in the delectron density and of the lattice parameter a 0 as well [205]. Thus, transition metal monoand bimetallic carbide, nitride and phosphide catalysts have been tested successfully in the HDS, HDN and HDO of oil and bio-oils [206][207][208][209][210][211]. Specifying on natural triglycerides and fatty acids few contributions suggest that this kind of catalysts is indeed promising.…”

Preparation of Ni-Mo 2 C/carbon catalysts and their stability in the HDS of dibenzothiophene

“…The presence of the 2 nd metal has also been shown to provide synergistic effects in the case of Co added to Mo2C when used for the chemo-selective reduction of nitroarenes, with the Co-Mo2C/AC catalyst having significantly higher activity than the Mo2C/AC alone [29]. Moreover, the bimetallic carbides formed in the presence of Mo and other transition metals [30,31] such as Fe, Co and Ni, show effective catalytic activity in hydrotreating reactions.…”
