“…Moreover, addition of ceria causes an improvement in both CO 2 conversion and CH 4 selectivity [41, [108][109][110]. Thus, the catalyst properties result from the synergistic effect between the metal active sites and the promoters.…”

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.

“…In addition to the direct exploitation of natural gas, the catalytic conversion of stoichiometric syngas (H 2 + CO) into methane (the so-called synthetic natural gas (SNG)) provides a promising way to supply this clean fuel in the area with few resource of natural gas [1][2][3][4][5][6][7][8][9]. Moreover, this SNG process has also been applied to remove trace CO molecules to purify the hydrogen for the fuel cell and the ammonia synthesis [10,11].…”

“…CO methanation as a useful technology to synthesize natural gas from syngas, has attracted much attention from both academia and industry in the last decade [1,2]. Since Sabatier and Senderens' pioneering work in 1902 on discovering methane formation by the reaction of carbon monoxide and hydrogen over a nickel catalyst [3], great efforts have been made to produce high-efficiency catalysts retaining high activity at low-temperature (ca.…”
