“…Metal oxides are the most common supports for the methanol synthesis catalysts, and their properties greatly affect the catalyst activity in several ways. The non-metallic supports, including metal organic frameworks (MOFs), porous silica materials, layered double hydroxides (LDHs), carbon materials, metal carbides, graphene, and porous polymers, have also been investigated (Rodriguez et al, 2015;Wang et al, 2015;Díez-Ramírez et al, 2016;Fan and Wu, 2016;Liu et al, 2016;Din et al, 2018;Sun et al, 2018;Witoon et al, 2018;Mureddu et al, 2019 (Toyir et al, 2009;Zhan et al, 2014;Hu et al, 2018).…”

Heterogeneous catalytic hydrogenation of carbon dioxide (CO2) to methanol is a practical approach to mitigating its greenhouse effect in the environment while generating good economic profits. Though applicable on the industrial scale through the syngas route, the catalyst of Cu/ZnO/Al2O3 suffers from a series of technical problems when converting CO2 to methanol directly, which include low single-pass conversion, low methanol selectivity, requiring high pressure and fast deactivation by the reverse water gas shift reaction. Over the years, intensive research efforts have been devoted to proffering solutions to these problems by modifying the existing catalyst or developing new active catalysts. However, the open question is if this type of widely used industrial catalyst still promising for CO2 methanolizing reaction or not? This paper reviews the history of the methanol production in industry, the impact of CO2 emission on the environment, and analyzes the possibility of the Cu/ZnO-based catalysts for the direct hydrogenation of CO2 to methanol. We not only address the theoretical and technical aspects but also provide insightful views on catalyst development.

“…Although it is unanimously recognized the peculiar functionality both of copper and zinc oxide in the mechanism of CO 2 activation, for a further development of the catalytic system, the need for other metal oxides into the catalyst composition is also required, so to realize multimetallic systems more active than bimetallic catalysts in the formation of MeOH, which will be then dehydrated into DME. Really, many studies have already reported the unique features of various metals added in the catalyst composition as promoters of Cu-Zn based catalysts for the CO 2 -to-MeOH hydrogenation reaction, like Al [ 53 , 54 , 55 , 56 ], Mn [ 57 , 58 ], Cr [ 59 ], Au [ 60 ], Zr [ 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 ], Pd [ 69 , 70 , 71 ], La [ 55 , 72 , 73 ], Si [ 74 , 75 ], Ce [ 55 , 76 ], Ga [ 77 , 78 ], V [ 79 ], carbon [ 80 , 81 , 82 ] or mixtures among them [ 55 , 83 , 84 , 85 , 86 ] revealing a superior performance of Zr, Al and Ga in terms of activity, selectivity and stability.…”

This review reports recent achievements in dimethyl ether (DME) synthesis via CO2 hydrogenation. This gas-phase process could be considered as a promising alternative for carbon dioxide recycling toward a (bio)fuel as DME. In this view, the production of DME from catalytic hydrogenation of CO2 appears as a technology able to face also the ever-increasing demand for alternative, environmentally-friendly fuels and energy carriers. Basic considerations on thermodynamic aspects controlling DME production from CO2 are presented along with a survey of the most innovative catalytic systems developed in this field. During the last years, special attention has been paid to the role of zeolite-based catalysts, either in the methanol-to-DME dehydration step or in the one-pot CO2-to-DME hydrogenation. Overall, the productivity of DME was shown to be dependent on several catalyst features, related not only to the metal-oxide phase—responsible for CO2 activation/hydrogenation—but also to specific properties of the zeolites (i.e., topology, porosity, specific surface area, acidity, interaction with active metals, distributions of metal particles, …) influencing activity and stability of hybridized bifunctional heterogeneous catalysts. All these aspects are discussed in details, summarizing recent achievements in this research field.

“…Figure 3 shows the X-ray diffraction (XRD) result of the Cu foil substrates and GO powder prepared by the hydrothermal method at 200 for 3 h. All the diffraction peaks in the XRD patterns of samples match well with those of cubic-phase Cu 2 O (JCPDS No.78-2076). Three peaks centered in XRD result at 43°, 50°, and 73°, refer to the (111), (200), and (220) planes of metallic copper (Fan & Wu 2016), can be clearly observed, which suggest that the Cu foil substrates were not fully utilized in these samples, meaning that there is still copper which not yet transformed to Cu 2 O. Four new characteristic diffraction peaks at 29°, 36°, 42°, and 74° in the composites correspond to the (110), (111), (200) and (311) crystalline planes of cubic Cu 2 O (de Brito et al 2015)ethanol, formaldehyde, acetaldehyde, and acetone was monitored during UV-visible radiation for 3h at +0.20V (vs. Ag/AgCl reference (Figure 3(a)).…”

The process of carbon dioxide (CO 2) reduction by using efficient non-precious-metal catalyst to make the process be economical has brought a comprehensive research in the area. In this study, graphene layer in copper foil was easily synthesized using hydrothermal method at temperature 200°C in 3 h duration. Diffraction peaks in XRD at around 29°, 36°, 42° and 74° in the composites correlate to the (110), (111), (200) and (311) crystalline planes of cubic cuprous oxide (Cu 2 O), while peak at 27° showed the carbon graphitic peak. Raman confirms the presence of the graphene layer on Cu 2 O. Photoelectrochemical performance test of Graphene/Cu 2 O demonstrated that the photoelectrocatalyst showing the photocurrent density 9.6 mA cm-2 at-0.8V vs Ag/AgCl. This study demonstrated a potential of semiconductor-based hybrid electrode for an efficient photoelectrocatalytic of CO 2 reduction.
