Summary: Dry reforming of methane is an efficient way to utilize carbon dioxide. This study utilized mesoporous silica support SBA-15 and microporous silica support beta as catalyst supports, and obtained highly dispersed Ni nanoparticles on Ni-SBA-15 and Ni-beta catalysts prepared by ammonia evaporation method. The Ni-SBA-15 and Ni-beta catalysts showed excellent catalytic activity, with a CO2 conversion of ca. 89 % and a CH4 conversion of ca. 84 % at 700 degrees C and nearly 100 % conversions at 800 degrees C. The mesopores of SBA-15 provided confinement for Ni nanoparticles, preventing Ni sintering and carbon deposition. However, the smaller pore size of beta hindered the introduction of Ni into its micropores, leading to more intensive Ni sintering and carbon deposition.

Summary: Plasma-assisted dry reforming of methane is a promising method to produce syngas with unity H2/CO ratio. The design of efficient catalyst materials is of great importance to establish a match between CH4 and CO2 activation rates. Addition of La to the highly ordered mesoporous 10Ni5LaAl-one pot catalyst enhanced reducibility of Ni2+ species and promoted Ni dispersion, resulting in the highest catalytic activity and cokeresistance ability. Stability performance was achieved due to higher discharge power, efficient capacitance, and lower apparent activation energy of CO2 under plasma condition. A possible reaction mechanism was proposed for the 10Ni5LaAl-one pot catalyst during plasma-catalytic dry reforming process.

Summary: Ni-M-Al (M = K, Na, Li) LDH-derived catalysts were evaluated for biogas dry reforming, showing differences in acidity and sintering resistance among the catalysts. The NiLi catalyst exhibited higher resistance to sintering and deactivation mainly due to carbon deposition, while NiK and NiNa catalysts were mainly deactivated by sintering during reactions. Different carbon species were produced by the catalysts depending on the reaction conditions.

Summary: Dry reforming of methane (DRM) is a green alternative for utilizing greenhouse gases and producing syngas. The main limitations of DRM are catalyst sintering and coking. Recent studies have focused on Ni-based catalysts for DRM due to economic constraints on noble metal-based catalysts. Mesoporous silica (MS) supported catalysts show promise due to their high surface areas, thermal stability, and easy availability. However, research on MS as a catalyst support for DRM is still limited.

Summary: This study investigates the use of Ni/Al2O3 catalysts for dry reforming of methane, with a focus on the effects of different promoters on catalyst stability. Higher iron loading on the catalyst leads to lower coke formation during dry reforming. Additionally, promoters with high CO2 affinity can accelerate catalyst oxidation during regeneration, ultimately leading to sintering and increased coke formation. Promoters with significant CO2 interaction are more effective on sintered catalyst samples compared to unpromoted Ni/Al2O3.

Summary: In this study, nickel- and iron-modified titanium dioxide (Ni-Fe/TiO2) catalysts were investigated for the dry reforming of methane (DRM) at 550 degrees C. The addition of Fe was found to decrease the conversion of both CO2 and CH4, and XPS results showed changes in the surface nickel and iron species. Characterization techniques, including TGA and Raman spectroscopy, indicated that Fe addition greatly inhibited coke formation and in situ DRIFTS confirmed the formation of carbonate species, which aided in the removal of deposited coke.

Summary: In this study, an in-situ hydrothermal growth method was used to preliminarily grow hematite on the already prepared iron oxide catalyst layer on the exterior of nickel foam, and gadolinium was further doped to form a three-dimensional coral-like structure. The optimized Gd-Fe2O3 catalyst shows excellent electrocatalytic performance in the oxygen evolution reaction, requiring only 245 mV to achieve a current density of 10 mA/cm2, with a smaller Tafel slope (48 mV/dec) and stability (10 mA/cm2 @50 h). The enhanced performance is attributed to the coral-like three-dimensional shape, which exposes more active sites and a higher surface area. Future nanostructured catalysts for OER can be intelligently designed using the simple method employed in this study.

Summary: The study evaluated the effect of a mesoporous Ni60%SiO2(Comm) catalyst, which has octahedral-shaped NiO particles, on the synthesis gas production via steam and dry reforming of a model biogas mixture. Compared to a standard Ni5%SiO2 catalyst, Ni60%SiO2(Comm) showed different reducibility behavior and shape transformation, resulting in higher reactivity and lower carbon deposition. The high-coke resistance of Ni60%SiO2(Comm) was attributed to the annealing effect during H-2(g) treatment, which yielded mesoporous metallic Ni-0 nanorods with H-2(g) storage capacities.
