“…To address this defect, metal-non-metal oxides (M x -NM y ), such as carbon-based nanomaterials, have been tried for induction heating. Mohanty et al [95] optimized the catalyst structure of carbon nanofibers/multilayer graphene (CNFs/FLG) supported Ni nanoparticles (NPs) by adjusting chemical vapor deposition parameters for the characteristics of CO 2 methanation under induction heating mode. They prepared CNFs with a specific herringbone shape, thus achieving a high edges-to-graphitic plane ratio in the support, which allows a very low nickel loading (10%) at relatively low temperatures (360 °C) to produce a high CO 2 conversion of 85% and a high selectivity of 99.6%.…”

CO2 capture and conversion technology are highly promising technologies that definitely play a part in the journey towards carbon neutrality. Releasing CO2 by mild stimulation and the development of high efficiency catalytic processes are urgently needed. The magnetic field, as a thermodynamic parameter independent of temperature and pressure, is vital in the enhancement of CO2 capture and conversion process. In this review, the recent progress of magnetic field‐enhanced CO2 capture and conversion is comprehensively summarized. The theoretical fundamentals of magnetic field on CO2 adsorption, release and catalytic reduction process are discussed, including the magnetothermal, magnetohydrodynamic, spin selection, Lorentz forces, magnetoresistance and spin relaxation effects. Additionally, a thorough review of the current progress of the enhancement strategies of magnetic field coupled with a variety of fields (including thermal, electricity, and light) is summarized in the aspect of CO2 related process. Finally, the challenges and prospects associated with the utilization of magnetic field‐assisted techniques in the construction of CO2 capture and conversion systems are proposed. This review offers a reference value for the future design of catalysts, mechanistic investigations, and practical implementation for magnetic field enhanced CO2 capture and conversion.

“…Ni impregnated on graphene supports with 3D structure were also prepared and investigated for the methanation of CO 2 [ 13 , 14 ]. FLG connected by carbon nanofibers (CNF) gives rise to a mesoporous 3D carbon structure with very good properties to host and stabilize the NiNPs [ 13 ]. Several parameters, including CNF synthesis conditions (which lead to CNF with varying diameters), as well as different Ni loadings, were tested.…”

In the context of an increased interest in the abatement of CO2 emissions generated by industrial activities, CO2 hydrogenation processes show an important potential to be used for the production of valuable compounds (methane, methanol, formic acid, light olefins, aromatics, syngas and/or synthetic fuels), with important benefits for the decarbonization of the energy sector. However, in order to increase the efficiency of the CO2 hydrogenation processes, the selection of active and selective catalysts is of utmost importance. In this context, the interest in graphene-based materials as catalysts for CO2 hydrogenation has significantly increased in the last years. The aim of the present paper is to review and discuss the results published until now on graphene-based materials (graphene oxide, reduced graphene oxide, or N-dopped graphenes) used as metal-free catalysts or as catalytic support for the thermocatalytic hydrogenation of CO2. The reactions discussed in this paper are CO2 methanation, CO2 hydrogenation to methanol, CO2 transformation into formic acid, CO2 hydrogenation to high hydrocarbons, and syngas production from CO2. The discussions will focus on the effect of the support on the catalytic process, the involvement of the graphene-based support in the reaction mechanism, or the explanation of the graphene intervention in the hydrogenation process. Most of the papers emphasized the graphene’s role in dispersing and stabilizing the metal and/or oxide nanoparticles or in preventing the metal oxidation, but further investigations are needed to elucidate the actual role of graphenes and to propose reaction mechanisms.

“…High Ni-doped heterogeneous catalysts are also known to have high intrinsic activity, high CH 4 selectivity, high availability, and low cost 19 but metal particle sintering and carbon formation on the catalyst surface at high temperatures are regarded as their main drawbacks 20 , 21 . So, several supports, such as Al 2 O 3 , the commonly used support with nickel 22 , SiO 2 23 , 24 , TiO 2 25 , and porous materials such as metal–organic frameworks (MOFs) 26 , 27 , zeolites 28 , 29 , carbon nanotubes 30 , 31 , carbon nanofibers 32 , 33 , MCM-41 34 and SBA-15 11 are used with nickel for this reaction.…”

The CO2 methanation technique not only gives a solution for mitigating CO2 emissions but can also be used to store and convey low-grade energy. The basic character and large surface area of mesoporous carbon nitride, (MCN), are considered promising properties for the methanation of CO2. So, a series (5–20 wt.%) of Ni-doped mesoporous carbon nitride catalysts were synthesized by using the impregnation method for CO2 methanation. the prepared catalysts were characterized by several physicochemical techniques including XRD, BET, FT-IR, Raman spectroscopy, TEM, TGA analysis, Atomic Absorption, H2-TPR, and CO2-TPD. The catalytic performance was investigated at ambient pressure and temperature range (200–500 °C) using online Gas chromatography system. The prepared catalysts showed good performance where 15%Ni/MCN exhibited the best catalytic conversion and methane yield with 100% methane selectivity at 450 °C for investigated reaction conditions.
