Fig. 4: Catalytic performance of selected materials.
From: Copper-zirconia interfaces in UiO-66 enable selective catalytic hydrogenation of CO2 to methanol
a Rates of methanol (MeOH) production (orange bars), methanol selectivity (green bars) on selected catalysts at 250 °C and 32 bar, and activation energy (Ea, pink points). b Arrhenius plots for methanol production on selected catalysts. The colors of the lines match the colors of the names of the materials. c Methanol and CO production on Cu/UiO-66-a. d Rate of methanol production on Cu/UiO-66-a as a function of time on stream for reaction conditions of 250 °C, 32 bar and CO2/H2/N2 = 7/21/1 mL/min. e The methanol and CO selectivity as functions of CO2 conversion for Cu/UiO-66-a at 190 °C and 32 bar. The CO2 conversion is varied by changing the gas space velocity.
