Hydrogen is seen as one of the energy sources of the future. However, hydrogen synthesis and transportation are major challenges to tackle. One realistic option is to use of non-hazardous organic molecules as hydrogen carriers “Liquid Organic Hydrogen Carriers” (LOHCs). Among these LOHCs, formic acid is very promising as its volumetric hydrogen densities is 30% higher than hydrogen compressed at 700 bar. Catalysts capable of dehydrogenating concentrated solutions of formic acid are needed to further develop formic acid as a LOHC. We reported on the implementation of efficient and robust iridium catalysts for the dehydrogenation of aqueous and neat formic acid. Experimental and theoretical studies have evidenced the involvement of the ligand in the catalytic process.
