“…When the loading was increased beyond 10 wt%, the conversion of CO 2 and space-time yield of methanol (STY MeOH ) decreased due to the agglomeration of active metals led to reduce copper oxides to metallic Cu 0 , which is a crucial active metal for synthesis of methanol [54]. As well as, Deerattrakul et al [54] have mentioned that his results have given the highest STY MeOH under the lowest operating pressure comparing to previously published works [55][56][57][58]. The rGO reduced by hydrazine played very significant role in the enhanced performance of the CuZn/ rGO catalyst [54].…”

-Climate change and global warming have become a challenging issue affecting not only humanity but also flora and fauna due to an intense increase of CO 2 emission in the atmosphere which has gradually led to amplification in the average global temperature. Hence, a number of mechanisms have been promoted to diminish the atmospheric commutation of carbon dioxide. One of the well-known techniques is Carbon Capture and Storage (CCS) which mechanism is based on capture and storage vast quantities of CO 2 , as well as Carbon Capture and Utilization (CCU) which mechanism is based on CO 2 conversion to liquid fuels (e.g. methanol, hydrocarbons, carbonate, propylene, dimethyl ether, ethylene, etc.). Particularly, methanol (CH 3 OH) is a key feedstock for industrial chemicals, which further can be converted into high molecular alternative liquid fuels. In this regard, hydrogenation of CO 2 is one of the promising, effectual and economic techniques for utilization of CO 2 emission. Nevertheless, the reduction/activation of CO 2 into useful liquid products is a scientifically challenging issue due to the complexities associated with its high stability. Thus, various catalysts have been applied to reduce the activation energy of the hydrogenation process and transform CO 2 into value-added products. Thereby, this review article highlights the progress and the recent advances of research investigation in Cu and Fe-based catalytic conversion of CO 2 , reaction mechanisms, catalytic reactivity, and influence of operating parameters on product efficiency.

“…A synergism between Cu 0 and Cu + sites is the most adopted explanation for the activity of Cu/ZnO-promoted catalysts [38,61,67,68]; however, Cu 0 sites [69,70] and/or Cu-Zn alloy [71][72][73] have been proposed to have a catalytic role as well.…”

“…Many unconventional preparation routes have been adopted to obtain Cu-ZnO catalysts with improved activity, selectivity, resistance to poisons, and enhanced lifetime [38,[74][75][76][77][78]. In this frame, the SG method was largely adopted in order to increase the metal surface area along with the total surface area [79,80].…”

“…The Cu-based catalysts were prepared by co-precipitation and impregnation, and the effect of MW on both preparation methods was studied: as a whole, the catalysts prepared by MW-assisted synthesis showed better Cu dispersion and enhanced catalytic activity in terms of both CO 2 conversion and CH 3 OH yield, especially when a single-step MW-assisted method was adopted [38]. The catalysts were characterized by X-Ray Diffraction (XRD), H 2 temperature programmed reduction (TPR), N 2 adsorption/desorption isotherms at −196 • C, CO 2 temperature-programmed desorption (TPD), adsorption calorimetry, and X-ray Photoemission Spectroscopy (XPS).…”

Abstract:The most recent progress obtained through the precise use of enabling technologies, namely microwave, ultrasound, and mechanochemistry, described in the literature for obtaining improved performance catalysts (and photocatalysts) for CO 2 hydrogenation, are reviewed. In particular, the main advantages (and drawbacks) found in using the proposed methodologies will be discussed and compared by focusing on catalyst design and optimization of clean and efficient (green) synthetic processes. The role of microwaves as a possible activation tool used to improve the reaction yield will also be considered.
