Tetherball: A heterogeneous, mesoporous silica‐tethered iridium catalyst (Ir‐PN/SBA‐15) containing a bidentate iminophosphine ligand is synthesized for the hydrogenation of CO 2 to formic acid in aqueous solution. This new recyclable catalyst exhibits high activities to formic acid production under mild conditions [60 °C, 4.0 MPa total pressure (H 2 /CO 2 =1:1)].
