Direction to practical production of hydrogen by formic acid dehydrogenation with CpIr complexes bearing imidazoline ligands

A Cp*Ir complex with a bidentate pyridyl-imidazoline ligand achieved the evolution of 1.02 m 3 of H 2 /CO 2 gases by formic acid dehydrogenation without any additives or adjustments in the solution system. The pyridyl-imidazoline moieties provided the optimum pH to be 1.7, resulting in high activity...

Description
Summary:A Cp*Ir complex with a bidentate pyridyl-imidazoline ligand achieved the evolution of 1.02 m 3 of H 2 /CO 2 gases by formic acid dehydrogenation without any additives or adjustments in the solution system. The pyridyl-imidazoline moieties provided the optimum pH to be 1.7, resulting in high activity and stability even at very acidic conditions. A Cp*Ir complex with pyridyl-imidazoline achieved the quantity production of 1 m 3 of H 2 /CO 2 gases from only HCO 2 H in water without any additives.
