Fig. 5: Adsorption energies (ΔEads in kJ/mol) of CO2 at the Cu/UiO-66-a interface.
From: Copper-zirconia interfaces in UiO-66 enable selective catalytic hydrogenation of CO2 to methanol
a Cu only sites, b Zr4+-O2- sites on the Zr6O8 nodes in a bidentate bridging mode, c Zr4+-O2-- Zr4+ sites on the Zr6O8 nodes in a tridentate bridging mode, and d Cu-Zr4+ interfacial sites.
