“…A number of studies have been carried out on this subject, which can be divided into two categories-methanolmediated and non-methanol-mediated reactions. 104,105 In the methanol-mediated approach, CO 2 and H 2 react over Cu-Zn-based catalysts to produce methanol, which is subsequently transformed into other hydrocarbons such as gasoline. 106 In spite of considerable efforts made in the development of composite catalysts, this approach usually yields light alkanes as major products owing to the further catalytic hydrogenation of the alkenes.…”

Owing to the increasing emissions of carbon dioxide (CO 2 ), human life and the ecological environment have been affected by global warming and climate changes. To mitigate the concentration of CO 2 in the atmosphere various strategies have been implemented such as separation, storage, and utilization of CO 2 . Although it has been explored for many years, hydrogenation reaction, an important representative among chemical conversions of CO 2 , offers challenging opportunities for sustainable development in energy and the environment. Indeed, the hydrogenation of CO 2 not only reduces the increasing CO 2 buildup but also produces fuels and chemicals. In this critical review we discuss recent developments in this area, with emphases on catalytic reactivity, reactor innovation, and reaction mechanism. We also provide an overview regarding the challenges and opportunities for future research in the field (319 references).

Fischer–Tropsch Synthesis: Deuterium Kinetic Isotope Study for Hydrogenation of Carbon Oxides Over Cobalt and Iron Catalysts

The hydrogenation of CO 2 using Pt promoted Co/c-Al 2 O 3 and doubly (Cu, K) promoted iron catalysts exhibits an inverse isotope effect (r H /r D \ 1). The observed inverse isotope effect for hydrogenation of CO 2 shows that hydrogen addition to CO 2 should be involved in the kinetically relevant step. The systematic increase of inverse isotope effect with carbon number of products obtained during H 2 -D 2 -H 2 switching experiments suggests the possible existence of a common intermediate (CH x O) for hydrogenation of CO 2 over both cobalt and iron FT catalysts. The magnitude of the inverse isotope effect is lower for CO 2 compared to CO hydrogenation under similar reaction conditions. The deuterium isotope effect does not provide a definite conclusion regarding the mechanism which CO 2 hydrogenation follows (alkyl, enol, or alkylidine mechanisms).

“…Primarily, these can be divided into two categories: the methanol mediated and the non-methanol mediated [2,3]. In the methanol mediated hydrocarbon synthesis carbon dioxide and hydrogen react on Cu-Zn based catalysts to produce methanol which is subsequently transformed into other hydrocarbons like gasoline (by MTG process), dimethyl ether, etc., However, in spite of considerable efforts made in the development of composite catalysts, this method usually gives light alkanes as major hydrocarbon products because the methanol synthesis catalyst further hydrogenates the alkenes [4].…”

Fischer–Tropsch Synthesis by Carbon Dioxide Hydrogenation on Fe-Based Catalysts

et al. 2008

Impregnated and co-precipitated, promoted and unpromoted, bulk and supported iron catalysts were prepared, characterized, and subjected to hydrogenation of CO 2 at various pressures (1-2 MPa) and temperatures (573-673 K). Potassium, as an important promoter, enhanced the CO 2 uptake and selectivity towards olefins and long-chain hydrocarbons. Al 2 O 3 , when added as a structural promoter during co-precipitation, increased CO 2 conversion as well as selectivity to C 2? hydrocarbons.
