“…The experimental results fully confirm the predictions from the computational screening. On the other hand, Ni-Fe alloys, also tested for CO 2 methanation, have not shown results concordant with those here discussed [219,220]. This, in our opinion, could be due to the different operational conditions adopted in the investigations.…”

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.

“…To study the effect of N-doped interlayers on the electrochemically induced growth and surface area degradation of catalytic NPs, Pt nanoparticles were deposited 32,33 on the benchmark CNTs as well as on the N-CNTs support materials. Particle growth trajectories were measured in situ using SAXS.…”

“…The production of methane from CO and CO 2 consists of several elementary reaction steps that sum up to overall reactions (1) and (2). Previous studies that have dealt with mechanistic aspects of catalytic CO conversion can be classifi ed into two categories: carbide mechanism and CO insertion mechanism [8,18,19].…”

“…The solid catalysts commonly used for methane production are based on transition metals supported on metal oxides, such as alumina, titanium dioxide, and zeolite [2][3][4][5]. Even though the catalysts consisting of a noble metal, such as ruthenium, rhodium or platinum [2,6], nickel-based catalysts have been the most widely studied because nickel is cheap and easily available and shows high activity [5,[7][8][9]. One of the disadvantages of the nickel-based catalysts may be that relatively high temperatures are needed to maintain the catalytic activity for methane production.…”

Plasma-catalytic hydrogenation of CO and CO 2 for producing methane was investigated with a catalyst-packed dielectric barrier discharge reactor. The characteristics of methane production from CO/H 2 or CO 2 /H 2 gas mixture were examined with bare alumina, TiO 2 /alumina, Ni/alumina, and Ni-TiO 2 /alumina under plasma and non-plasma conditions. The results obtained with bare alumina and TiO 2 /alumina suggest that either plasmainduced gas-phase reactions or photocatalytic reactions hardly contribute to the conversion of CO and CO 2 . The nonthermal plasma was found to have a promotive effect on the conversion of CO and CO 2 only when nickel-loaded catalysts such as Ni/alumina and Ni-TiO 2 /alumina were used, implying that the nonthermal plasma serves to promote the dissociation of carbon-oxygen bonds of CO and CO 2 adsorbed on the active sites of the catalysts, known as the slowest step of the reaction.
