A NiMo‐ceria‐zirconia catalyst was developed for an inert‐substrate‐supported tubular single cell running on isooctane fuel. The tubular single cell consisted of an inert porous yttira‐stabilized zirconia (YSZ) supporter, Ni‐Ce0.8Sm0.2O1.9 (Ni‐SDC) anode, YSZ/SDC bilayer electrolyte and La0.6Sr0.4Co0.2Fe0.8O3−δ (LSCF) cathode. The NiMo‐ceria‐zirconia catalyst was packed in the tubular channel of the single cell as a reforming unit. With application of the catalyst in the tubular cell, the mixture of isooctane and air can be efficiently reformed to simple syngas (a mixture of hydrogen and carbon monoxide) at 750 °C. Compared to electrochemical performance of the single cell without the catalyst, applying the catalyst increased maximum power density of the single cell from 240 to 306 mW cm−2, and the single cell exhibited significantly improved stability during the 18 h performance test. The results suggest the feasibility of applying the NiMo‐ceria‐zirconia catalyst for operating the tubular single cell using isooctane fuel.

“…The Ni‐Mo/CeO 2 catalysts can promote C–O activation and inhibit the C‐C breaking. Another possible reason is that the formation of the new crystalline phases NiMoO 4 , MoO 3 and MoO 2 improves selectivity and yields of octane, as verified by the XPS spectra . On the contrast, the lower hydrogenation activity of CoMo/CeO 2 resulted from the strong Co and Mo antagonism effect despite the introduction of active Mo sites.…”

“…In order to overcome these limitations, various efforts have been devoted to modify the catalysts. Mo has been successfully introduced to Ni‐Mo/CeO 2 ‐ZrO 2 catalyst for partial oxidation of iso‐octane to reduce coking . The researchers considered that the addition of Mo could improve the coking resistance and then enhanced the long‐term stability of Ni‐based catalyst.…”

Hydrodeoxygenation of Octanoic Acid over the Mo–Doped CeO₂‐Supported Bimetal Catalysts: The Role of Mo

et al. 2018

Nonsulfided CeO2‐supported different metal catalysts were synthesized, characterized and evaluated in the hydrogenation of octanoic acid with a batch reactor at the temperature of 280 oC and initial H2 pressure of 3 MPa. The effect of Mo species was revealed by comparing Mo‐doped catalysts with Mo‐free catalysts. The catalytic results show that the CeO2 supported Ni catalyst doped with Mo exhibit much higher catalytic activity and octane selectivity than the catalysts without dopants. Additionally, the influences of Mo and Ni mass ratio on the conversion of octanoic acid and the selectivity of heptane and octane over CeO2‐based catalysts were also discussed. Ni species seemed beneficial for the deoxygenation reaction to form C7 alkane, while the doping of Mo favored the hydrodeoxygenation path to C8 alkane via dehydration‐hydrogenation of the octanol intermediate.

Solid oxide fuel cells (SOFCs) that can operate on hydrocarbon fuels offer an efficient and cost‐effective solution for electricity generation. However, broader commercialization of SOFCs is hindered by inadequate performance and limited durability due to the sluggish hydrocarbon reforming/oxidation kinetics and coking on the SOFC anode. Here it has been reported that these findings in design, synthesis, and characterization of a novel anode catalyst Ba(Zr0.8Y0.2)0.9(Ni0.5Ru0.5)0.1O3‐δ (BZYNR) that overcomes the problems, enabling direct utilization of nearly dry hydrocarbon fuels (e.g., methane, ethanol, and iso‐octane with only 3 vol% H2O) with exceptional power output for over 1000 h on both button cells and tubular cells. The outstanding performance of BZYNR is attributed to the high activity of hydrocarbon reforming and the accelerated water‐mediated carbon cleaning process on Ni‐based SOFC anode.
