摘要：

We herein report that an iron (Fe) complex bearing a tetradentate PNNP ligand catalyzes photochemical carbon dioxide (CO2) reduction to produce mainly carbon monoxide (CO) together with formic acid (HCO2H) combined with a photosensitizer. The structurally bulky phosphine moieties stabilized the catalyst and improved its durability over a few days (similar to 72 h) to give the turnover number (TON) of 397. measurements allowed us to observe the direct electron transfer from a reduced photosensitizer to the Fe catalyst.
