Hydrodeoxygenation of Furfural over Unsupported, SiO2‐supported or Metal‐promoted Mo Carbides: Tunning the Selectivity between 2‐Methylfuran and C10 Furoins Diesel Precursors

“…In another work, however, the α‐MoC formation was only observed for unsupported Mo carbides promoted with Ni, Pd, and Pt, which were able to promote the hydrogen and methane activation at lower temperatures during temperature‐programmed carburization compared to Cu and Co metals [57] . Nonetheless, several Ni‐promoted Mo carbides exhibited only the formation of β‐Mo 2 C phase [33,36,60–63] …”

The structural evolution of Mo2C and Mo2C/SiO2 under dry reforming of methane conditions: morphology and support effects

“…This observation indicates that a dynamic oxidation-recarburization process may in principle take place under DRM conditions, 7 yet it has been reported that addition of transition metals such as Ni is required to increase the rate of recarburization, in order to match the oxidation rate. 12,13 Phase evolution by MCR-ALS analysis of in situ XAS data A quantitative analysis of the in situ XANES data was performed via the MCR-ALS method combined with principal component analysis. This method allowed us to assess the phase evolution during carburization and DRM, as well as to extract the main components that describe the dynamics of the investigated materials.…”

“…7,8 For instance, catalysts based on molybdenum carbide (Mo 2 C) are active in DRM. 7,[9][10][11][12][13] Advantages of carbide-based catalysts include high resistance to coking or sulfur poisoning as well as sintering resistance, 14,15 however, the high oxophilicity of early TMCs is a limitation as it often results in the deactivation of TMCbased catalysts under oxidizing atmospheres (CO 2 ) at high temperatures via the formation of oxide phases. More specifically, depending on the operating conditions, (the total pressure, the partial pressure of CO 2 , temperature and the space velocity) bulk β-Mo 2 C DRM catalysts can be oxidized to MoO 2 which has been linked to their deactivation.…”

Evaluating metal oxide support effects on the RWGS activity of Mo2C catalysts

“…Recently, transition metal carbides, such as molybdenum and tungsten, have attracted significant attention, as they exhibit activity that mimics the activity of noble metals for a variety of catalytic reactions. [29][30][31] For example, Mo 2 C has been reported as a catalyst for many reactions including CO 2 hydrogenation, 32,33 methane reforming and aromatization, [34][35][36][37] the hydrogen evolution reaction, 38,39 and the RWGS reaction. 16,30 In particular, Porosoff et al reported that potassium promoted Mo 2 C supported on γ-alumina was an excellent catalyst for the RWGS reaction, demonstrating a CO 2 conversion of 18.1% at 300 °C and 19.4 bar with a CO selectivity of 95.9%.…”
