“…Cu 0 was beneficial in methanol formation, exhibiting higher hydrogenation capability. As clarified by our previous research on this new low-temperature synthesis method, [16][17][18][19][20][21][22][23] metallic Cu 0 was the active site for the hydrogenation of formic ester in forming methanol. From the TPR findings, the burnt catalyst with finely dispersed Cu oxide was easier to be reduced, as shown by its behavior in C 0.5 , C 1.4 , and C 1.8 .…”

“…The effects of reaction temperature on lowtemperature methanol synthesis are investigated in Table 3. In our former work, [16][17][18][19][20][21][22][23] 443 K was found to be the best temperature when co-precipitation and impregnation method were used to prepare Cu/ZnO catalysts with a series of different alcohols as solvent and promoters. When the sol-gel combustion method was used, the effect of reaction temperature on the activity and methanol selectivity of the burnt catalysts was investigated.…”

“…A new method for low-temperature methanol synthesis from CO/CO 2 /H 2 on Cu/ZnO-based catalysts using alcohol as solvent and a promoter is proposed by the present authors; the methanol is produced at 443 K and 5.0 MPa. [16][17][18][19][20][21][22] A small amount of CO 2 (5%) in the syngas could promote the conversion of CO. The used alcohol solvent contains a small amount of water, so this new low-temperature process could directly use low-grade syngas containing CO 2 and H 2 O without purification.…”

Metallic Cu/ZnO catalysts were prepared by a sol-gel auto-combustion method using metal nitrates and citric acid. The activity of the burnt catalysts was investigated for low-temperature methanol synthesis from CO 2-containing syngas using ethanol as solvent and a promoter. The activity and the methanol selectivity of the burnt Cu/ZnO catalysts were closely related to metallic Cu 0 surface areas and Cu crystalline sizes, and were greatly influenced by the reaction temperature. The effects of M/CA mole ratios on the properties of the burnt catalysts and catalytic activity were systematically studied by Thermogravimetry, Differential Thermal Analysis, Fourier Transform-Infrared, Raman spectrum, X-Ray Diffraction, Scanning Electron Microscope-Energy Dispersive Spectroscopy, Temperature-Programmed Reduction, Brunauer-Emmett-Teller, and N 2 O chemisorption techniques. The fierceness degree and the temperature of the whole catalyst preparation process were closely related to the balance between the combustion and the pyrolysis processes respectively. Upon continually increasing the citric acid content in the initial precursors, the combustion process became much milder, but excess citric acid in the chelated compound could lead to more violent amorphous carbon oxidation and much more severe pyrolysis of organic residues.

“…We propose this low-temperature energy-saving methanol synthesis from CO, CO 2 , and H 2 on Cu-ZnO-based catalyst using alcohol as solvent and promoter, by which methanol is produced at 443 K and 5.0 MPa. [24][25][26][27][28][29] CO 2 in the syngas could promote the activity of the reaction. This greenhouse gas was consumed in the reaction, making it environmentally friendly.…”

A series of Cu–ZnO catalysts were prepared by using a solid‐state combustion method with metal nitrates and citric acid. This method was simple, waste water free, and did not require a reduction step. If the precursors were burnt in an argon atmosphere, H2 and CH4 were emitted in the decomposition of metal citrate complexes and acted as reducing agents to yield metallic Cu from Cu2+ in the chelated compounds. Analysis of XRD patterns revealed that the precursors burnt at 523 K for 1 h in the argon atmosphere were converted into pure Cu species. TPR analysis of the burnt catalysts without further reduction illustrated that almost no hydrogen was consumed. However, a part of amorphous carbon and carboxylates were left in the burnt catalysts. Compared with formerly reported Cu–ZnO catalysts prepared by the sol–gel combustion method, the catalysts prepared by the solid‐state combustion method had higher activity and methanol selectivity.
