“…Additionally, the synergetic effect between La 2 O 3 –ZrO 2 and Ni–Mo 2 C can be regarded as another factor that accelerates the DRM conversion rate. In another study, Majewski et al observed improved carbon tolerance when yttria-stabilized ZrO 2 was used as support in the combined steam and dry reforming of methane. They pointed out that an excessive amount of Mo 2 C could decrease the catalytic activity of Ni–Mo 2 C in DRM.…”

Hydrogen, with its high energy content and environmental-friendly properties, is considered an effective energy carrier in addition to fossil fuels. Methane reforming represents a major method of hydrogen production, although the applied catalysts often suffer from coke deposition and metal sintering at high operating temperatures. Transition-metal carbides (TMCs), particularly molybdenum carbides (Mo x C), possess features such as Pt-like behaviors, affinity with oxidants such as CO2 and H2O, and a strong metal–support interaction for metal dispersion and stabilization, rendering them great prospective candidates for catalyzing the methane reforming reactions (MRRs). This review focuses on the recent applications and challenges of TMCs in MRRs, with an emphasis on the strategies to improve their performance by (1) engineering the operational conditions, (2) designing a dual M–Mo x C (M = Ni or Co etc.) active site, (3) dispersing M–Mo x C on supports, and (4) generating a M–Mo x C/MoO x C y interface in situ. The present review will provide guidance for the future design of efficient catalysts for H2 production from MRRs.

“…Significant efforts have been dedicated to the development of vanadium-and molybdenum-based components. Increasing Mo fraction in NieMo catalysts significantly improves resistance to coking although reduces catalytic activity [60]. The Ni(11 wt.%)-Mo(3 wt.%)-YSZ reforming layer at the Ni-YSZ anode ensured a stable performance of the isooctane-fueled cell, whereas a similar cell without a reforming layer failed after 12 h [61].…”

“…Considering its dual functionality as the anode support and the anode catalyst, the calciumdoped ceria is applied as the porous ceramic substrate in the independent catalyst layer in this work. Furthermore, the NiMo-based metal catalyst has demonstrated high activity towards the catalytic partial oxidation of the hydrocarbon fuel [22]. This NiMo catalyst is incorporated into the independent catalyst layer for the internal reforming SOFCs.…”

A porous ceramic support is designed as a multi-functional independent catalyst layer for solid oxide fuel cells (SOFCs) running on liquid hydrocarbon fuel. The layer consists of a highly porous Ce 0.9 Ca 0.1 O 2−δ ceramic backbone and active NiMo catalysts, which could be integrated into the conventional Ni metal containing the anode for internal reforming of the hydrocarbon fuel. Compared to conventional catalyst layers sintered on the anodes, this independent catalyst layer could be simply assembled on top of the anode without additional sintering, thereby avoiding the mismatch of the thermal expansion coefficient between the catalyst layer and the anode and improving stability of a single cell. Moreover, a current collector layer could be inserted between the catalyst and the anode to enhance current collection efficiency and electrochemical performance of the single cell. At 750 ℃, the independent catalyst layer displays high activity towards the catalytic decomposition of methanol, and the single cell could achieve the maximum power density of 400-500 mW•cm −2 in dry methanol. Furthermore, by employing the independent catalyst layer, the single cell offers additional in-situ catalyst regeneration capability under the methanol operation mode. Feeding 10 mL•min −1 air into an anode channel for 5 min is found to be effective to burn out carbon species in the catalyst layer, which reduces the degradation rate of the cell voltage by orders of magnitude from 2.6 to 0.024 mV•h −1 during the operation of 360 h in dry methanol. The results demonstrate the significance of the independent catalyst layer design for direct internal reforming methanol fuel cells.
