Ammonia Methanation of Carbon Dioxide with a Hybrid Catalyst
Journal of Chemical Engineering of Japan, 2023 Ammonia methanation is a reaction that synthesizes methane directly from carbon dioxide and ammonia. The Sabatier reaction, which synthesizes methane by hydrogenating carbon dioxide, requires a cooling facility in the reactor due to its large heat value.

Construction of Sabatier Volcanoes for CO<sub>2</sub> Hydrogenation to C1-2 Oxygenates Using Data-Efficient Machine Learning. [PDF]
Adv Sci (Weinh)A new data‐efficient framework combining DFT calculations, a neural network model, and automated graph analysis of catalytic reaction networks is proposed and applied to CO2 hydrogenation on transition metal nanoparticles. The analysis shows how efficient C2 oxygenate production requires a balance between CHx formation, C–C coupling, protonation, and ...
