Hydrogen Generation from Formic Acid Decomposition with a Ruthenium Catalyst Promoted by Functionalized Ionic Liquids

A series of amine-functionalized ionic liquids is prepared and used for hydrogen generation by the selective catalytic decomposition of formic acid. A good catalytic activity was obtained using an iPr2NEMimCl–HCOONa system at 40 °C. The use of volatile organic amines is thus avoided, simplifying the purification of hydrogen
