“…Most studies focused on high-temperature CO 2 reforming of CH 4 . However, only a few reports were published [18,19]. Therefore, there is a big gap and huge challenge on the application of low-temperature (< 700°C) CO 2 reforming of CH 4 .…”

Catalytic dry reforming of methane (DRM) is a promising way for renewable syngas production due to the utilization of both CO2 and CH4 greenhouse gases. Current approaches were made to improve the catalytic activity and coke resistance by introducing a second metal into the Ni‐based catalytic system. This bimetallic catalytic system showed a significant improvement in coke resistance due to the synergistic effect of both metals towards the reaction. This review summarizes recent developments in bimetallic catalysts in DRM which focused on the evaluation of catalysts, deactivation studies, and reaction mechanisms of developed bimetallic catalysts.

“…However, the disadvantage of using noble-metals-based catalysts is their high cost [5][6][7]. Ni-based catalysts, due to good catalytic activity and low cost, have been widely investigated for the DRM reaction [8][9][10]. However, Ni-based catalysts are prone to carbon deposition and metal sintering during DRM [11,12].…”

Ni nanoparticles encapsulated within La 2 O 3 porous system (Ni@La 2 O 3 ), the latter supported on SiO 2 (Ni@La 2 O 3 )/SiO 2 ), effectively inhibit carbon deposition for the dry reforming of methane. In this study, Ni@La 2 O 3 /SiO 2 catalyst was prepared using a one-pot colloidal solution combustion method. Catalyst characterization demonstrates that the amorphous La 2 O 3 layer was coated on SiO 2 , and small Ni nanoparticles were encapsulated within the layer of amorphous La 2 O 3 . During 50 h of dry reforming of methane at 700 • C and using a weight hourly space velocity (WHSV) of 120,000 mL g cat −1 h −1 , the CH 4 conversion obtained was maintained at 80%, which is near the equilibrium value, while that of impregnated Ni-La 2 O 3 /SiO 2 catalyst decreased from 63% to 49%. The Ni@La 2 O 3 /SiO 2 catalyst exhibited very good resistance to carbon deposition, and only 1.6 wt% carbon was formed on the Ni@La 2 O 3 /SiO 2 catalyst after 50 h of reaction, far lower than that of 11.5 wt% deposited on the Ni-La 2 O 3 /SiO 2 catalyst. This was mainly attributed to the encapsulated Ni nanoparticles in the amorphous La 2 O 3 layer. In addition, after reaction at 700 • C for 80 h with a high WHSV of 600,000 mL g cat −1 h −1 , the Ni@La 2 O 3 /SiO 2 catalyst exhibited high CH 4 conversion rate, ca. 10.10 mmol g Ni −1 s −1 . These findings outline a simple synthesis method to prepare supported encapsulated Ni within a metal oxide porous structure catalyst for the dry reforming of methane reaction.

“…The co-conversion of methane and carbon dioxide to valueadded chemicals represents an important subject in C 1 chemistry from energy and environmental perspectives, [1] but it is very difficult because of the inherent stability of both CH 4 and CO 2 .D ry reforming of methane (DRM) with CO 2 has been developed for generation of syngas (CO + H 2 ) [2] that can be converted to desired products by either alcohols synthesis or Fischer-Tropsch processes. [3] However,s uch indirect route is highly energy intensive.T he design of catalysts that can achieve the direct co-conversion of CH 4 and CO 2 thus becomes appealing driven by the economical consideration.…”

Direct conversion of methane with carbon dioxide to value‐added chemicals is attractive but extremely challenging because of the thermodynamic stability and kinetic inertness of both molecules. Herein, the first dinuclear cluster species, RhVO3−, has been designed to mediate the co‐conversion of CH4 and CO2 to oxygenated products, CH3OH and CH2O, in the temperature range of 393–600 K. The resulting cluster ions RhVO3CO− after CH3OH formation can further desorb the [CO] unit to regenerate the RhVO3− cluster, leading to the successful establishment of a catalytic cycle for methanol production from CH4 and CO2 (CH4+CO2→CH3OH+CO). The exceptional activity of Rh‐V dinuclear oxide cluster (RhVO3−) identified herein provides a new mechanism for co‐conversion of two very stable molecules CH4 and CO2.
