From: Direct catalytic hydrogenation of CO2 to formate over a Schiff-base-mediated gold nanocatalyst
H2 (black square) and CO2 (red circle) pressure-dependent initial reaction rates. Reaction conditions: 5 mg Au/SiO2-Schiff catalyst, 10 mL reagent, 10 mmol NEt3, 600 rpm, H2O/CH3OH (20:80 vol/vol). The solution was pressurized at room temperature with CO2 and completed with H2 to the desired pressure. The system was heated at 90 °C and stirred until a desired formate concentration was reached (0.5–3 h). The initial TOF is calculated by the Supplementary Equation 2
