Abstract

Carbon dioxide hydrogenation to methane is efficiently achieved using ruthenium nanoparticles (Ru NPs) prepared and stabilized in task-specific ionic liquids. 1-Octyl-3-methylimidazolim perfluorobutanesulfonate [C₈mim][NfO] is the best ionic liquid media producing 84% yield of methane at 150 °C. Other fluorinated anions based ionic liquids exhibited a greater influence on the methane production. In parallel, carbon monoxide is selectively produced in a small amount for the ionic liquid media containing trifluoroacetate and mesylate anions. It is known that ionic liquids strongly contribute to higher CO₂ solubility as well as the formation and stabilization of Ru NPs. The catalytic system maintains some activity at least after 5 recycling studies and a promissory improvement can be achieved using a further continuous-flow system.
