“…Therefore, an appropriate substitution in the amount of Co and Ni was required to provide equality on the conversions of CH 4 and CO 2 to synthesis gas. Similarly, in the development of a Ni‐Co catalyst, Nagaoka et al , Gonzalez‐delaCruz et al , Ay and Üner , Seguota et al , Valderrama et al , Gao et al , Bian and Kawi , Xu et al , and Estephane reported that the coke formation can be remarkably reduced with the addition of a suitable amount of Co.…”

“…Apart from Ni and Co composition, preparation methods also play a significant role in achieving high activity and stability of bimetallic Ni-Co catalysts. Modifying conventional impregnation or precipitation methods by the addition of dispersing agents, such as oleylamine/oleic acid (OAm/OAc) [25], urea [27], or CD [28], resulted in homogeneous distribution of metal particles and excellent synergistic effect between Co and Ni, and thus led to high catalytic activity. Alternatively, the application of advanced preparation methods may become a new direction for optimizing synergistic effects of the catalyst, thus achieving high catalytic activity.…”

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.

“…Alloying Ni with other metals like Cu, Fe and Co received increased attention for usage in various catalytic reactions, because alloying with second metal form a solid solution which improved catalytic activity . Ni‐based catalysts containing second metal exhibited significant changes in catalyst activity and selectivity as compared to monometallic Ni catalysts in many reactions ,. The authors have suggested that the changes in the catalytic properties induced by second metal addition to Ni may be caused by changes in the electronic and/or geometric properties of the homogeneous bimetallic particles.…”

This article provides a critical review of Ni-based catalysts employed in high temperature and ultra-high temperature water gas shift reaction (WGS) for hydrogen production and methane suppression. The promotional role of nature and type of active metal and support for WGS reaction is discussed with respect to activity and selectivity. This review mainly covers the recent strategic catalytic formulations like promotion with alkali metals, alloying with another metal and core@-shell-like structures for suppressing methanation during WGS reaction. The change in nature and strength of CO adsorption over modified Ni-surfaces is discussed using available in situ CO-DRIFTS results. The various WGS reaction and CO methanation pathways are also presented together with insights gained from computational DFT studies.[a] Dr.

“…Therefore, the DRM is often performed under at a temperature higher than >800 º C 10, 57-60 , and very little research on the DRM has been conducted at low temperatures (<550 º C). However, the hightemperature DRM not only has the drawback of high cost but also problems such as catalyst sintering and coke formation [61][62][63][64][65] , it is therefore highly desirable to develop novel catalysts to enable the DRM process to occur at low temperature conditions.…”

The current study reviews the recent development in the direct conversion of methane into syngas, methanol, light olefins, and aromatic compounds. For syngas production, nickelbased catalysts are considered as a good choice. Methane conversion (84%) is achieved with nearly no coke formation when the 7% Ni-1%Au/Al2O3 catalyst is used in the steam reforming of methane (SRM), whereas for dry reforming of methane (DRM), a methane conversion of 17.9% and CO2 conversion of 23.1% are found for 10%Ni/ZrOxMnOx/SiO2 operated at 500 o C. The progress of direct conversion of methane to methanol is also summarized with an insight into its selectivity and/or conversion, which shows that in liquid-phase heterogeneous systems, high selectivity (>80%) can be achieved at 50 o C, but the conversion is low. The latest development of nonoxidative coupling of methane (NOCM) and oxidative coupling of methane (OCM) for the production of olefins is also reviewed. The Mn2O3-TiO2-Na2WO4/SiO2 catalyst is reported to show the high C2 yield (22%) and a high selectivity toward C2 (62%) during the OCM at 650 o C. For NOCM, 98% selectivity of ethane can be achieved when a tantalum hydride catalyst supported on silica is used. In addition, the Mo-based catalysts are the most suitable for the preparation of aromatic compounds from methane.
