A porous organic polymer with aminopyridine functionalities was designed to fabricate a stable, atomically dispersed Ir catalyst. This Ir-based SAC exhibits excellent catalytic activity during the liquid phase hydrogenation of CO2 to formate, with a turnover number as high as 25,135 representing the best performance yet for a heterogeneous conversion of CO2 to formate. The chemical structure of the Ir SAC is analogous to that of a homogeneous mononuclear complex catalyst, representing an intermediary between heterogeneous and homogeneous catalysis.
