“…The calculated STY of methanol reached 0.12 g MeOH /(g cat h), while the conversion of CO 2 and STY of methanol decreased to 12.1% and 0.1 g MeOH /(g cat h) over CZA-oxalic acid-1.00. CZA-urea-1.00 has shown the lowest activity for hydrogenation of CO 2 with 3.2% CO 2 conversion and 0.022 g MeOH /(g cat h) STY MeOH , which could be resulted to the smaller exposed Cu surface area and larger particle size of CuO, and the formation of ZnAl 2 O 4 [27]. Consequently, it was revealed that the CO 2 conversion and STY of methanol increased with the added amount of citric acid during catalyst preparation and the maximum conversion of CO 2 reached 16.2% over CZA-citric acid-1.25.…”

“…Liu et al [24,25] suggested that copper metal and low valence of Cu (Cu þ and Cu dþ ) may affect the catalytic activity of Cubased oxide catalysts. Most recent studies [26][27][28][29][30] declare that resolution of the geometrical and electronic structures of the active site is the first step toward an efficient catalyst design with high selectivity and activity.…”

-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 series of catalysts constituted of mixed copper and zinc oxides supported on alumina were prepared by co-precipitation method. The cooper content was in the 10-90 wt.% range. Their catalytic behavior in the hydrogenation of carbon dioxide to methanol was investigated at high pressure (up to 75 bars). The catalysts were characterized by elemental analysis, N2-adsorption, N2O-chemisorptions, and X-ray diffraction (XRD). The catalysts showed a clear activity in the hydrogenation reaction that could be correlated to the surface area of the metallic copper and to the reaction pressure. The CuO/ZnO/Al2O3 catalyst with a Cu/Zn/Al weight ratio of 60/30/10, exhibits the highest carbon dioxide conversion and methanol selectivity. Finally, a mechanism pathway has been proposed on copper active sites of (Cu 0 /Cu I ) oxidation state.

In order to overcome the photocatalytic degradation reaction with a need for light excitation, the exploration of a catalyst for the organic degradation reaction without light has become one of the core challenges in catalysis and pollution control. Here we report a novel CuNiSeS nanosheet catalyst with a hexagonal structure by a feasible preparation method. The structure and composition of CuNiSeS were well characterized by X-ray diffractometry and electron microscopy, and X-ray pho- [a]
