Highly efficient hydrogen evolution by decomposition of formic acid using an iridium catalyst with 4,4′-dihydroxy-2,2′-bipyridine
Abstract
The efficient evolution of CO-free hydrogen by the decomposition of formic acid using iridium catalyst with 4,4′-dihydroxy-2,2′-bipyridine as a ligand in H2O was demonstrated. The highest catalytic activity (turnover frequency (TOF) of up to 14000 h−1 at 90 °C) and an almost complete consumption of formic acid were obtained for the catalytic system. Furthermore, it was found that hydrogen could be generated even at elevated pressures. We discuss the possibility of a cycle for CO2 as a hydrogen carrier by combining the decomposition of formic acid (evolution of H2) with the hydrogenation of bicarbonate (fixation of CO2 and storage of H2) using the iridium catalyst.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
