“…According to the research conducted by Deerattrakul et al [54], 10 wt% CuZn/rGO catalyst performed the highest activity for the CO 2 hydrogenation with a 26% CO 2 conversion, 51% CH 3 OH selectivity, and 424 ± 18 mg MeOH at 250°C and 15 bar after 5 h on stream of CO 2 and H 2 . When the reaction was completed, the spent catalyst was reevaluated its structure using XRD in order to examine the stability of rGO.…”

“…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].

-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.

“…Recently, the enhanced durability and activity [41][42][43][44][45][46] can be achieved by the Cu 2 O-based photocatalysts. Among them, the incorporation of graphene with the 2D sp 2 -hybridized carbons has received much attention due to its high electron mobility [47], theoretical surface area [48], and chemical stability [49]. For instance, a microwave-assisted chemical method was proposed to prepare Cu 2 O/reduced graphene oxide (rGO) nanocomposites which have improved activity and stability toward the photocatalytic reduction of CO 2 [50].…”

A simple solution-chemistry method has been investigated to prepare crystal cuprous oxide (Cu 2 O) incorporated with reduced graphene oxide (designated as Cu 2 O-rGO-x, where x represents the contents of rGO = 1%, 5% and 10%) in this work. These Cu 2 O-rGO-x composites combine the prospective advantages of rhombic dodecahedra Cu 2 O together with rGO nanosheets which have been studied as visible-light-sensitive catalysts for the photocatalytic production of methanol from CO 2 . Among the Cu 2 O-rGO-x photocatalysts, the methanol yield photocatalyzed by Cu 2 O-rGO-5% can be observed to be 355.26 µmol g −1 cat, which is ca. 36 times higher than that of pristine Cu 2 O nanocrystal in the 20th hour under visible light irradiation. The improved activity may be attributed to the enhanced absorption ability of visible light, the superior separation of electron-hole pairs, well-dispersed Cu 2 O nanocrystals and the increased photostability of Cu 2 O, which are evidenced by employing UV-vis diffuse reflection spectroscopy, photoluminescence, scanning electron microscopy/transmission electron microscopy and X-ray photoelectron spectroscopy, respectively. This work demonstrates an easy and cost-effective route to prepare non-noble photocatalysts for efficient CO 2 recovery in artificial photosynthesis.
