Figure 1. (A) 3D plots based on reaction temperature, reaction pressure [P(CO2+H2)], and associated TON or TOF for various reported homo- and heterogeneous catalysts applied for O-formylation of methanol (see Supplementary Tables 1 and 2 for details); (B) O-formylation of alcohols catalyzed by the Ir/POP-Phen catalyst. TON: Turnover number; TOF: turnover frequency; Ir/POP-Phen: porous phenanthroline-based polymer-supported single-iridium-atom catalyst.
