Iridium Catalyst Immobilized on Crosslinked Polyethyleneimine for Continuous Hydrogen Production Using Formic Acid

Graphical Abstract The Front Cover shows illustrates the practical continuous-flow system for hydrogen production from formic acid using an iridium-immobilized catalyst based on polyethyleneimine (PEI) showcased as a yellow solid powder. It also depicts power generation through a fuel cell. The catalytic activity, expressed as turnover frequency (TOF value), is 73 200 h-1, with durability exceeding 2000 h without any degradation. The system has achieved continuous electric power generation for over 5 h on a laboratory scale. More information can be found in the Research Article by K. Sawahara et al.
