a Comparison of the CH3OH generation rates of PC-In2O3 through the direct hydrogenation of CO2 and indirect transformation of CO2 with DMC as a bridge. Reaction conditions through direct hydrogenation of CO2: catalysts (20 mg), THF (5 mL), 1 h, 100 °C, and 2 MPa (25% CO2 + 75% H2). Reaction conditions through indirect transformation: catalysts (20 mg), CH3OH (5 mL), 100 °C, Step I: 1 MPa CO2 and 2 h; Step II: 2 MPa H2 and 0.5 h. b Comparison of the CH3OH generation rates of PC-In2O3 through the indirect transformation of CO2 and other state-of-the-art catalysts (see Supplementary Table S2 for more details).
