“…Carbon nanotube-supported Mo 2 C (Mo 2 C/CNT) and active carbon-supported Mo 2 C (Mo 2 C/AC) catalysts were reported as active and selective in the one-step conversion of vegetable oils into branched diesel-like hydrocarbons [40,44]. When supported on AC, Mo 2 C was found to be more active than the unsupported Mo 2 C for the HDO of methyl stearate, a model compound [44].…”

“…The catalysts obtained showed different crystalline phases depending upon both the Mo precursor used and the support (Figure 2). High-angle annular dark-field (HAADF) scanning transmission electron microscopy (STEM) was used to characterize the structure of Mo2C/CNTs prepared by carbothermal hydrogen reduction [40]. The distribution of brighter spots indicated that the Mo2C particles ( Figure 3) are uniformly dispersed on CNTs supports.…”

“…20% Mo 2 C/CNT was tested and compared to 5% Pd/CNTs and 5% Pt/CNTs for the one-step hydrodeoxygenation and isomerization of vegetable oils (Scheme 2) [40]. 20% Mo 2 C/CNTs was more active than 5% Pd/CNTs and 5% Pt/CNTs (90%, 41% and 32%, respectively) in the transformation of methyl palmitate at 240 • C. The authors observed that the main reaction route of higher aliphatic esters on Mo 2 C is hydrodeoxygenation, compared to noble metals (Scheme 1).…”

Transition metal carbides have been utilized as an alternative catalyst to expensive noble metals for the conversion of biomass. Tungsten and molybdenum carbides have been shown to be effective catalysts for hydrogenation, hydrodeoxygenation and isomerization reactions. The satisfactory activities of these metal carbides and their low costs, compared with noble metals, make them appealing alternatives and worthy of further investigation. In this review, we succinctly describe common synthesis techniques, including temperature-programmed reaction and carbothermal hydrogen reduction, utilized to prepare metal carbides used for biomass transformation. Attention will be focused, successively, on the application of transition metal carbide catalysts in the transformation of first-generation (oils) and second-generation (lignocellulose) biomass to biofuels and fine chemicals.
