• Novel tri-N-heterocyclic carbene (triNHC)-coordinated iridium catalysts (Ir­(triNHC)) were employed for generating clean hydrogen and useful C n acids from biomass-derived alcohols. The high efficiency and fast rate of hydrogen production (maximum turnover frequency = 13,080 h–1 and 485 L of H2/g-cat·h) from sustainable ethylene glycol were elucidated by the increased electron-richness of Ir­(triNHC) complexes where three NHC ligands were coordinated to an iridium­(I) ion. Elaborated mechanistic studies support the proposed reaction mechanisms forming H2 and C n acids. This Ir­(triNHC)-catalyzed process converting sustainable alcohols to useful fuels and chemicals is a promising carbon-neutral process.
