Tuning electron back-donation to switch reaction pathway in CO2 hydrogenation [PDF]

Nature Communications
CO2 hydrogenation over earth-abundant Ni catalysts is attractive for CO-based fuel synthesis, but Ni intrinsically favors methanation. Here we show that ordered Ni3Sn2 intermetallics tune Ni–CO electron back-donation and switch CO2 hydrogenation from CH4

New mechanism insight for the hydrogenation of CO/CO2 gas mixtures to hydrocarbons over iron-based catalyst

Catalysis Communications, 2021
Iron-based catalysts are the most suitable candidates for converting CO2 or CO2-rich syngas to hydrocarbons. However, several issues about the mechanism of CO2 hydrogenation are still unclear.

Mechanistic insights to drive catalytic hydrogenation of formamide intermediates to methanol via deaminative hydrogenation

Frontiers in Energy Research, 2023
Amine-promoted hydrogenation of CO2 to methanol typically proceeds via a formamide intermediate when amines are used as additives or if the hydrogenation is performed in carbon capture solvents.

Comparative study on the effect of different copper loading on catalytic behaviors and activity of Cu/ZnO/Al2O3 catalysts toward CO and CO2 hydrogenation

Heliyon, 2021
The ternary Cu/ZnO/Al2O3 (CZA) catalysts having different Cu loading were prepared by the co-precipitation method. Then, they were used in CO and CO2 hydrogenation to produce methanol under atmospheric pressure at 250 °C. The high Cu loading CZA catalyst
