文摘

Simple 1-alkyl(aryl)-3-methylimidazolium N-bis(trifluoromethanesulfonyl)imidate salts that possess verylow vapor pressure, high density, and thermal stability and are not inflammable can add reversibly 6-12hydrogen atoms in the presence of classical Pd/C or Ir⁰ nanoparticle catalysts and can be used as alternativematerials for on-board hydrogen-storage devices. These salts can hold up to 30 g L^-1 of hydrogen at atmosphericpressure, which is twice that compressed hydrogen gas can attain at 350 atm.
