Conversion of CO2 to methanol over bifunctional basic-metallic catalysts

Impact of the Local Environment of Amines on the Activity for CO2 Hydrogenation over Bifunctional Basic – Metallic Catalysts

“…During the last step of the cycle, the temperature was increased from 343 K to 413 K, which led to the desorption of strongly bound CO 2 followed by methanol and water as products. Other products such as CO or CH 4 were not observed within the detection limits [14] . The reaction showed a stable activity of the catalyst for 9 consecutive cycles (SI Figure 7).…”

“…In the last step the formamide undergoes selective hydrogenolysis yielding methanol, while recovering the primary amine. [14] In this work we present an integrated solid sorbent and catalyst, which adsorbs and selectively converts CO 2 to methanol and focus on the effect of structural and electronic properties on the activity of this material.…”

“…The reaction proceeds via a carbamate formed upon reaction of two amines with one CO 2 molecule and the corresponding formamide, formed by the reaction of the carbamate with H 2 . In the last step the formamide undergoes selective hydrogenolysis yielding methanol, while recovering the primary amine [14] …”

Infrared spectroscopic monitoring of solid-state processes

“…Due to the importance of the process, publications focused on IR monitoring of the sorption of CO 2 197–207 or methane 208–211 by solids are numerous. In principle, qualitative or semi-quantitative monitoring of the changes in solid samples due to gas sorption does not require any additional accessories.…”
