Selective hydrogenation of carbon dioxide (CO2) into value-added chemicals has aroused great interest. The chemical inertness of CO2 and diverse reaction pathways usually require the construction of enabled catalysts. To date, cobalt (Co) catalysts characteristic of metallic and/or divalent Co components show great potential for CO2 hydrogenation. To better regulate the CO2 hydrogenation, it is necessary to summarize the current progress of cobalt catalysts for selective hydrogenation of CO2. In this Perspective, first, hydrogenation of CO2 into methane over metallic Co sites is introduced. Second, hydrogenation of CO2 into methanol and C2+ alcohols is discussed by constructing mixed-valent cobalt sites. Third, hydrogenation of CO2 into light olefins and C5+ liquid fuels over cobalt-containing hybrid catalysts is introduced. Fourth, the reaction paths for selective hydrogenation of CO2 over cobalt catalysts are illustrated. Finally, the current challenges and prospects of cobalt-based nanocatalysts for hydrogenation of CO2 are proposed.

“…As compared to the “methanol-mediated” processes occurring over metal–oxide/zeolite catalysts, CO 2 -FT synthesis exhibits higher yields of olefins and lower selectivity to CO. , The selection of efficient promoters for iron catalysts seems to be the key for the selectivity control of this reaction. Alkaline metals, ,− copper, , manganese, ,, zinc, ,,, and cobalt − have been the most investigated promoters for iron CO 2 -FT catalysts. At the same time, very limited attention has been paid to the promotion of iron CO 2 -FT catalysts with other elements.…”

“…The presence of alloy on the catalyst surface promoted the in situ generations of iron-cobalt carbide, Co 2 C and θ-Fe 3 C phases. In addition to activity enhancement, inhibition of both CO 2 methanation and secondary hydrogenation of olefins were observed [132].…”

“…To improve catalyst efficiency in the formation of olefins by CO2 hydrogenation, several alternative methods to precipitation, such as electrospinning, microemulsion or microwave irradiation, were recently employed. Recently, a series of highly efficient ZnCo x Fe 2-x O 4 spinel catalysts were prepared by Xu et al via a single-source layered double hydroxide precursor route [132]. Compared to the bimetallic ZnFe 2 O 4 and ZnCo 2 O 4 systems, the ternary spinel catalyst ZnCo 0.5 Fe 1.5 O 4 showed excellent performance in the hydrogenation of CO 2 to light olefins: at a CO 2 conversion of 49.6%, the selectivity was 36.1%.…”

Catalysts for the Conversion of CO2 to Low Molecular Weight Olefins—A Review

et al. 2021

View full text Add to dashboard Cite

There is a large worldwide demand for light olefins (C2=–C4=), which are needed for the production of high value-added chemicals and plastics. Light olefins can be produced by petroleum processing, direct/indirect conversion of synthesis gas (CO + H2) and hydrogenation of CO2. Among these methods, catalytic hydrogenation of CO2 is the most recently studied because it could contribute to alleviating CO2 emissions into the atmosphere. However, due to thermodynamic reasons, the design of catalysts for the selective production of light olefins from CO2 presents different challenges. In this regard, the recent progress in the synthesis of nanomaterials with well-controlled morphologies and active phase dispersion has opened new perspectives for the production of light olefins. In this review, recent advances in catalyst design are presented, with emphasis on catalysts operating through the modified Fischer–Tropsch pathway. The advantages and disadvantages of olefin production from CO2 via CO or methanol-mediated reaction routes were analyzed, as well as the prospects for the design of a single catalyst for direct olefin production. Conclusions were drawn on the prospect of a new catalyst design for the production of light olefins from CO2.
