Metal (Mo, W, Ti) Carbide Catalysts: Synthesis and Application as Alternative Catalysts for Dry Reforming of Hydrocarbons—A Review

“…The most widely examined carbide is molybdenum carbide with cobalt or nickel carbides [19,20]; however, carbides WC, NbC, VC, and TiC have also been examined [19,21]. Other examples of application of carbides in catalysts are hydrogenolysis and isomerization of hydrocarbons [22], catalytic and electrocatalytic hydrogen generation [23][24][25], hydrocarbon reforming [26,27], carbon dioxide upgrading [23,28], hydrogenation [29], and aromatization [30]. Moreover, carbides of layered structures are receiving increased attention in gas sensing [31,32] and battery applications [27,33,34].…”

“…A carbon source may also be in solid form, and it acts as a reducing agent and support. Biochar [77], biomass [24], resins [78], and carbon nanotubes [79] have been investigated. Liang et al [78] investigated the effect of the preparation procedure on the formation of α-Mo 1-x C and β-Mo 2 C, and the solid mixture of α-Mo 1-x C and β-Mo 2 C. Molybdenum carbide was prepared by ion exchange, impregnation, and mechanical mixing of molybdate salt with a strong alkali anion exchange resin and heated under a hydrogen or argon atmosphere in a temperature range of 350 to 900 • C. They found that annealing under H 2 promotes the formation of the beta phase.…”

“…The carbide structure is reconstructed with the carbon element from the dissociation of methane; however, oxidation with CO 2 is more favorable [219]. The combination of molybdenum carbide with other metals: Ni [222], Co [223], and Fe [24], allows controlled dissociation paths of CO 2 and CH 4 , ensuring appropriate conditions for oxidation-recarburization cycles [47,224]. The introduction of other metals into the carbide catalyst results in the generation of more moles of hydrogen, leading to a higher H 2 /CO ratio in the outlet stream.…”

Graphene-Supported Fe/Ni, β-Mo2C Nanoparticles: Experimental and DFT Integrated Approach to Catalyst Development for Synergistic Hydrogen Production through Lignin-Rich Biomass Reforming and Reduced Shale Gas Flaring

“…Destabilization due to the graphene support alleviates blanket deposition of CH 4 and CO like molecules . It was observed that a higher loading concentration of TMs especially Fe leads to the synthesis of a carbon nanofiber (CNF)/carbon nanotube (CNT) support . Multiple reaction cycles over the graphene/CNF-supported catalyst leads to a graphene layer cover over the active sites.…”

“…This behavior has been studied in detail over 15 biomass-reforming cycles with 5% CH 4 and 1% CO 2 for catalyst stability, regeneration, and performance evaluation for hardwood biomass reforming. The Fe–Mo 2 C-GNS catalyst demonstrated excellent capacity for recycling and sustained activity despite the harsh reaction conditions and highly carbonaceous feedstock like biomass …”
