Iridium Single-Atom Catalyst Performing a Quasi-homogeneous Hydrogenation Transformation of CO2 to Formate

？ An aminopyridine-POP was designed to fabricate an atomically dispersed Ir catalyst ？ This Ir/AP-POP performs best for a heterogeneous transformation of CO2 to formate ？ A quasi-homogeneous structure and mechanism were demonstrated on the Ir/AP-PO
