摘要：

Modular but geometrically constrained ligands were used to investigate the impact of key ligand design parameters (charge and bite angle) on CO2 hydrogenation and formic acid dehydrogenation activity. These studies yielded an optimized catalyst that achieved over 118000 turnovers in CO2 hydrogenation, 247000 turnovers in HCO2H dehydrogenation, was applied in a hydrogen storage device used for 6 cycles of hydrogen storage/release without requiring changes in pH or solvent, and generated H-2/CO2 gas at a pressure of 190 atm from formic acid.
