+

ZnO and nitrogendoped carbon (NC) overcoated Febased catalysts (FeNC) were synthesized and evaluated in CO 2 hydrogenation reaction. The FeNC exhibited enhanced catalytic activity, stability, and high selectivity toward light olefins and C 5+ hydrocarbons. The olefins over paraffins ratio in the range of C 2C 4 increased 24 times from to compared with the benchmark Fe 3

The adsorption and decomposition reactions of carbon dioxide and methanol have been studied on clean Ag(100), O/Ag(100) and ZnO/Ag(100) surfaces. The clean Ag(100) surface itself is unreactive in so far as no lowpressure adsorption of either molecule is observed at ambient temperatures. At lower temperatures a wea

The presence of CO2 in gaseous fuel and feedstock stream of chemical reaction was always considered undesirable. High CO2 content will decrease quality and heating value of gaseous fuel, such as biohydrogen, which needs a practical approach to remove it. Thus, this work aims to introduce the first C3N4metal oxide hybrid for the CO2 cleaning application from a mixture of CO2H2 gas. The ...

Methanol synthesis from carbon dioxide at atmospheric ...

+

Methanol synthesis from CO2 and H2 was carried out over a Cu/ZnO catalyst (Cu/Zn = 3/7) at atmospheric pressure, and the surface species formed were analyzed by diffuse reflectance FTIR spectroscopy and temperature programmed desorption method. Two types of formate species and zinc methoxide were formed in the course of the reaction. Zinc methoxide was readily hydrolyzed to …

20210209· Zn 0 und Zn 2+ (ZnO) können anhand des ZnLMMSpektrums (Abbildung 2 D) unterschieden werden, in dem der gut aufgelöste Peak bei etwa 987,8 eV dem ZnO zugeordnet wird. Die Tatsache, dass ZnO als Hauptkomponente auf der Oberfläche der ZnNanoblättchen lokalisiert ist, stimmt gut mit der HRTEMAnalyse in Abbildung 1 F überein.

When calcined and reduced, the gerhardite precursors formed Cu/ZnO catalysts which showed better productivity for methanol synthesis from CO2 hydrogenation than a traditional malachite precursor, despite their larger CuO crystallite size determined by Xray diffraction. The solvents could be recovered by switching to the biphasic system after precipitation, to allow solvent recycling in the ...
