“…Recently, the confinement effect has been applied to promote the catalytic conversion of CO x by tuning the interaction of reactant molecules and active sites. [60,61] Mureddu et al synthesized Cu/ZnO@SBA-15 and Cu/ZnO/ ZrO 2 @SBA-15 catalysts by an innovative impregnation-sol-gel autocombustion combined strategy and tested them for carbon dioxide hydrogenation to methanol. The reaction results showed that the supported catalyst with the lowest Cu/Zn molar ratio (1.0 mol mol À 1 ) exhibits the best catalytic performance with a space-time-yield of methanol of 376 mg CH3OH h À 1 g cat À 1 , much more efficient than the unsupported catalyst (10 mg CH3OH h À 1 g cat À 1 ).…”

“…Interestingly, it was found that the confinement of the active phase in the SBA-15 structure enhances its ability to interact with H 2 and CO 2 , resulting in improved performance. [60] The deposition of a 2D layers on a metal surface has been considered as an efficient way in tuning the interaction of reactant molecule-metal and also surface reactivity by confinement effect. Wang et al systematically explored a novel nanospace constructed by placing a 2D graphitic carbon nitride (g-C 3 N 4 ) nanosheet over a Pt (111) surface through first-principles calculations.…”

Owing to the depletion of fossil reserves and the global warming by released greenhouse gas from the consumption of fossil resources, the catalytic conversion of carbon oxide (COx, including CO2 and CO) into fuels and high‐value chemicals has attracted tremendous interest in the field of catalysis. Developing high‐performance and practical catalysts with high activity, selectivity, and stability is of great importance but remains a huge challenge. A variety of new strategies were developed to take advantage of confinement effect to address the challenges that are relevant to the highly‐efficient transformation and utilization of COx by performing catalytic reactions in a confined space. The status on this issue can be divided into three aspects: improvement in catalytic activity, increase in catalytic selectivity and enhancement in catalytic stability. In this review, the progress in the field of promoted catalytic conversion of COx in confined spaces will be presented and discussed. Especially, the specific promoting mechanism in terms of the confinement effect for COx‐related transformations in confined spaces and the relationship between the impact of the confined space on the catalytic activity, selectivity, and stability regarding of COx conversions are highlighted. Finally, the future prospects on the opportunities and challenges of catalytic conversion of COx in confined spaces are outlined.

“…When the temperature increased to 250°C, the corresponding values changed to 13.4% and 13% respectively. In addition, other combinations of Cu and metal/metal oxides have been explored extensively in methanol synthesis field, such as Cu/Mg/Al [31], Cu/ZnO/ZrO2 [33,34]. For comparison's sake, the performances of other Mo2C related catalysts have also been listed in table 1 [29,30].…”

Mitigation of Anthropogenic CO2 emissions possess a major global challenge for modern societies. Herein catalytic solutions are meant to play a key role. Among the different catalysts for CO2 conversion Cu supported on molybdenum carbide is receiving increasing attention. Hence, in the present communication we show the activity, selectivity and stability of fresh-prepared -Mo2C catalysts and compare the results with those of Cu/Mo2C, Cs/Mo2C and Cu/Cs/Mo2C in CO2 hydrogenation reactions. The results showed that all the catalysts were active and the main reaction product was methanol. The results showed that copper-cesium and molybdenum effectively interact and that cesium promoted the formation of metallic Mo. While, the incorporation of copper is positive to improve the activity and selectivity to methanol, the presence of Mo0 phase was detrimental for the conversion and selectivity. Moreover, the catalysts promoted by cesium underwent redox surface transformations during the reaction that diminished their catalytic performance. The molybdenum phase in Cu/Mo2C changes during reaction leading to metallic molybdenum and tuning the catalytic activity.

“…Mesoporous materials, as SBA-15, of high specific surface area which favour the dispersion of the active phase Cu/ZnO have been also studied as supports for this purpose. The supporting of Cu/ZnO on SBA-15 [85,86] or on SBA-15 modified with ZrO 2 [85] has been studied. The catalytic behaviour of these materials indicated that the confinement of the Cu/ZnO particles in the SBA-15 structure improves its ability to interact with H 2 and CO 2 which results in better performance of the catalysts.…”

Technological approaches which enable the effective utilization of CO2 for manufacturing value-added chemicals and fuels can help to solve environmental problems derived from large CO2 emissions associated with the use of fossil fuels. One of the most interesting products that can be synthesized from CO2 is methanol, since it is an industrial commodity used in several chemical products and also an efficient transportation fuel. In this review, we highlight the recent advances in the development of heterogeneous catalysts and processes for the direct hydrogenation of CO2 to methanol. The main efforts focused on the improvement of conventional Cu/ZnO based catalysts and the development of new catalytic systems targeting the specific needs for CO2 to methanol reactions (unfavourable thermodynamics, production of high amount of water and high methanol selectivity under high or full CO2 conversion). Major studies on the development of active and selective catalysts based on thermodynamics, mechanisms, nano-synthesis and catalyst design (active phase, promoters, supports, etc.) are highlighted in this review. Finally, a summary concerning future perspectives on the research and development of efficient heterogeneous catalysts for methanol synthesis from CO2 will be presented.
