“…Among commercially available mesoporous carbon supports is sibunit, which is thermally and mechanically stable and has high sorption capacity. 64 However, this was contradictory with the utilization of sibunit, which has the lowest conversion among all of the carbon supports analyzed. This may be due to the way that the support is incorporated.…”

The global increase of greenhouse gas carbon dioxide (CO 2 ) affects the balance of the atmosphere by contributing vastly to global warming. CO 2 hydrogenation is an attractive way to use CO 2 for value-added product generation. Direct CO 2 conversion to synthetic fuels or gasoline fuel, although challenging, is deemed effective in reducing CO 2 . The adsorption energy of CO 2 on the catalyst surface is the limiting factor; hence, the metal−support interaction is established as key in formulating a catalyst with superior performance. Typically iron oxide catalysts were commonly used as a Fischer−Tropsch catalyst, although the CO 2 conversion is relatively low. This review aims to highlight the importance of choosing the most suitable support with desired acidity and reduction capability for adequate interaction with catalyst active sites to enhance the activity and selectivity of the existing metal oxide catalyst. Support incorporation methods on the surface metal−support interaction are also scrutinized and accompanied by the reaction parameters for higher conversion, and reactor setup parameters that may have influenced the selectivity are analyzed.

“…[15][16][17][18][19][20] Activated carbon or modern carbon materials are usually used as a carrier. [21][22][23][24][25][26][27] It is known [28][29][30] that metal particles deposited on carbon catalyze various reactions of the carbon carrier with hydrogen and carbon oxides. Therefore, the effect of the carbon support on the activity and selectivity of metaldeposited catalysts in organic reactions at the stages of both a N. D. Zelinsky Institute of Organic Chemistry, Russian Academy of Sciences, pre-activation and in situ reactions is the subject of numerous studies, and, in particular, in the development of new heterogeneous catalytic systems.…”

“…However, the target product was formic acid or formamide, which determined the choice of the catalysts (homogeneous Ru complexes) and the mode of operation. There is a number of our works devoted to the hydrogenation of CO 2 under supercritical conditions [ 28 , 29 , 30 , 31 , 32 , 33 , 34 ]. A supercritical media may enhance the catalyst activity and prolong its lifetime [ 34 ].…”

Reduction of CO2 with hydrogen into CO was studied for the first time on alumina-supported Co and Fe catalysts under supercritical conditions with the goal to produce either CO or CH4 as the target products. The extremely high selectivity towards methanation close to 100% was found for the Co/Al2O3 catalyst, whereas the Fe/Al2O3 system demonstrates a predominance of hydrogenation to CO with noticeable formation of ethane (up to 15%). The space–time yield can be increased by an order of magnitude by using the supercritical conditions as compared to the gas-phase reactions. Differences in the crystallographic phase features of Fe-containing catalysts cause the reverse water gas shift reaction to form carbon monoxide, whereas the reduced iron phases initiate the Fischer–Tropsch reaction to produce a mixture of hydrocarbons. Direct methanation occurs selectively on Co catalysts. No methanol formation was observed on the studied Fe- and Co-containing catalysts.
