“…[ 28 ] The XRD results of spent samples (Figure S6, Supporting Information) results showed the effect of Ru species on preventing the sintering of Ni–Mo particles and, subsequently, leading to less graphitic carbon deposition. [ 27,29–35 ] Our CO‐DRIFT findings (Figure S7, Supporting Information) also support the XRD and STEM results that the addition of Ru promoter with low loadings improves the dispersion of supported NiMo, forming more reactive sites and less coking.…”

In previous work, nickel–molybdenum (NiMo) nanoparticles supported on cerium–zirconium oxide (CZ) catalyst showed excellent catalytic activity and stability for liquid fuel reforming with an improved coking resistance compared with Ni/CZ. Lowering the temperature of solid oxide fuel cells (SOFCs) below 700 °C is vital, because they can reduce the material costs and thermal stresses of SOFCs. However, the performance of NiMo/CZ is insufficient when operated at temperatures below 750 °C. This work aims to improve the activity and coking resistance of NiMo/CZ at a temperature of 700 °C by adding a minimal amount (0.1 wt%) of Ru. The Ru‐promoted sample shows a high reforming activity for partial oxidation of isooctane at 700 °C. The X‐ray diffraction (XRD) and STEM indicate a smaller Ni crystallite size for NiMoRu/CZ catalyst, which would decrease its tendency to facilitate coke formation. The tubular SOFC with the NiMoRu/CZ as its internal reforming catalyst displays good power density output and performance stability at 200 mA cm−2.

“…[40][41][42][43][44] Ni has been used mainly for steam reforming reactions, and poorly for oxidation reactions. [45][46][47][48][49] However, to our knowledge using Ni/Al 2 O 3 , NiCeO 2 and Ni/Al 2 O 3 -CeO 2 catalysts with nano characteristics for the catalytic wet air oxidation of phenol in milder conditions has not been reported in the literature, so there was enthusiasm to investigate this nano structured system.…”

Bifunctional catalysts are widely used in the hydroisomerization of long‐chain n‐alkanes, which are of great significance in the production of high value‐added chemicals. Herein, the Ni/ZSM‐23‐W and Ni/ZSM‐23‐EG catalysts were prepared using water and ethylene glycol, respectively. The catalysts were characterized using XRD, SEM, TEM, NH3‐TPD, Py–IR, H2‐TPR, H2‐TPD, ICP–OES, and XPS, and their catalytic performance was evaluated by conducting the hydroisomerization of n‐hexadecane as a model reaction. It was revealed that the polarity of the impregnating solvent has a significant impact on the dispersion of Ni nanoparticles. When employing ethylene glycol as a solvent, a strong interaction occurred between NiOx and ZSM‐23 in the Ni/ZSM‐23‐EG catalyst, which facilitated the formation of small‐sized and well‐dispersed Ni nanoparticles. Consequently, the Ni/ZSM‐23‐EG catalyst demonstrated a strong hydrogenation capacity, yielding an impressive 72.9% of iso‐hexadecanes yield.
