“…108 The hydrogenation of CO 2 to DME has attracted great interest with several heterogeneous catalysts. 74,75,77,78,109–112 Direct CO 2 hydrogenation to DME is shown below:CO 2 + 6H 2 ⇌ CH 3 OCH 3 + 3H 2 OΔ H = −122.2 kJ mol −1 Cu–ZnO–Al 2 O 3 catalysts and a mesoporous HZSM-5 zeolite are used in DME synthesis, providing great resistance and improving the mass transfer process during the reactions. 113 Alvarez et al 114 reported that direct CO 2 hydrogenation to DME requires a bifunctional catalyst in order to perform methanol synthesis and methanol dehydration.…”

“…Therefore, water plays a major role in the acidic activity of catalysts, as it determines the strength and availability of methanol to these acidic sites and can be altered by thermal treatments or modification of metal-oxygen clusters in local structures [59]. The advanced adsorption process shows that, by choosing the right water absorber, it is possible to overcome the thermodynamic constraint [60]. Direct DME catalysts are susceptible to deactivation by oxidation, sintering, coke deposition, and contamination to impurities in the syngas, affecting the acidic sites of methanol dehydration [61,62].…”

Dimethyl ether (DME) is a synthetically produced alternative fuel to diesel-based fuel and could be used in ignition diesel engines due to increasing energy demand. DME is considered extremely clean transportation and green fuel because it has a high cetane number (around 60), low boiling point (−25 °C), and high oxygen amount (35 wt%) which allow fast evaporation and higher combustion quality (smoke-free operation and 90% fewer NOx emissions) than other alternative CO2-based fuels. DME can be synthesized from various routes such as coal, petroleum, and bio-based material (i.e., biomass and bio-oil). Dimethyl ether can be produced from CO2 to prevent greenhouse gas emissions. This review aims to summarize recent progress in the field of innovative catalysts for the direct synthesis of dimethyl ether from syngas (CO+H2) and operating conditions. The problems of this process have been raised based on the yield and selectivity of dimethyl ether. However, regardless of how syngas is produced, the estimated total capital and operating costs in the industrial process depend on the type of reactor and the separation method.

“…However, due to the thermodynamic stability of CO 2 , the formation of the C−H bond from CO 2 hydrogenation requires efficient catalysts and massive energy input including hydrogen source. [10][11][12] Apart from gaseous hydrogen, high-temperature water (HTW) could also be served as a hydrogen source. Due to the unique physical and chemical properties of HTW, the in situ hydrogen under hydrothermal conditions (200~400°C, 10~25 MPa) is more active than gaseous H 2 .…”

Converting CO2, a major component of greenhouse gas in the atmosphere, into value‐added fine chemicals is beneficial from environmental and economic aspects. Except for various methods for CO2 reduction such as thermal catalysis, photocatalysis, electrocatalysis and biological reduction, hydrothermal reduction of CO2 to organics is becoming a novel and promising strategy. The hydrogen formed in situ from high‐temperature water could avoid the serious issues of hydrogen storage and transportation. This paper summarizes the recent advances on CO2 conversion to formic acid with metal‐ and biomass‐based compounds under hydrothermal conditions mainly focusing on the role of high‐temperature water, autocatalysis mechanism of metal reductants, and interfacial catalysis mechanism of metal/metal oxides. The effects of several experimental variables including temperature, reaction time and pH of the solution on formic acid yield are systematically illustrated as well. Finally, future efforts for fundamental researches and industrial applications of hydrothermal CO2 reduction are discussed.
