“…Supported Ni catalysts are the most widely investigated materials for CO 2 methanation due to their high efficiency in CH 4 production and low cost [75][76][77][78][79][80][81][82][83][84][85][86][87][88][89]. A lot of supports have been investigated for Ni catalysts since, as is well known, the catalytic performance strongly depends upon the nature and properties of the support.…”

CO 2 methanation is a well-known reaction that is of interest as a capture and storage (CCS) process and as a renewable energy storage system based on a power-to-gas conversion process by substitute or synthetic natural gas (SNG) production. Integrating water electrolysis and CO 2 methanation is a highly effective way to store energy produced by renewables sources. The conversion of electricity into methane takes place via two steps: hydrogen is produced by electrolysis and converted to methane by CO 2 methanation. The effectiveness and efficiency of power-to-gas plants strongly depend on the CO 2 methanation process. For this reason, research on CO 2 methanation has intensified over the last 10 years. The rise of active, selective, and stable catalysts is the core of the CO 2 methanation process. Novel, heterogeneous catalysts have been tested and tuned such that the CO 2 methanation process increases their productivity. The present work aims to give a critical overview of CO 2 methanation catalyst production and research carried out in the last 50 years. The fundamentals of reaction mechanism, catalyst deactivation, and catalyst promoters, as well as a discussion of current and future developments in CO 2 methanation, are also included.

“…The methanation of CO 2 is more rapid and more selective compared with that of CO over Ni, Fe, Rh, and Ru catalysts [90]. Ni is the most studied and considered the most suitable catalyst for methanation of carbon oxides because of its high selectivity for CH 4 and its relatively low price [91][92][93][94]. Different support materials have been used for the dispersion of Ni and other active metals, including SiO 2 , Al 2 O 3 , TiO 2 , ZrO 2 , CeO 2 , and zeolite [95][96][97][98][99].…”

“…Conventional methanation processes involve nanostructured active metals on various supports (e.g. SiO 2 [2], ZrO 2 [3], Al 2 O 3 [4], carbon nanotubes [5]). Despite the existence of other elements at the research level, Ni remains the best choice for the active metal when considering activity, selectivity and price [6].…”

a b s t r a c tSorption enhanced CO 2 methanation is a complex process in which the key challenge lies in the combined optimization of the catalyst activity and water adsorption properties of the zeolite support. In the present work, improved nickel-based catalysts with an enhanced water uptake capacity were designed and catalytically investigated. Two different zeolite frameworks were considered as supports for nanostructured Ni, and studied with defined operation parameters. 5Ni/13X shows significantly increased, nearly three-fold higher, operation time in the sorption enhanced CO 2 methanation mode compared to the reference 5Ni/5A, likely due to its higher water sorption capacity. Both catalysts yield comparable CO 2 conversion in conventional CO 2 methanation (without water uptake). Regeneration of the catalysts performance is possible via a drying step between methanation cycles under both reducing and oxidizing atmospheres; however, operation time of 5Ni/13X increases further after drying under air.
