Optimizing Binding Energies of Key Intermediates for CO2

A bound system is typically at a lower energy level than its unbound constituents because its mass must be less than the total mass of its unbound constituents. For systems with low binding energies, this "lost" mass after binding may be fractionally small, whereas for systems with high binding energies, the missing mass may be an easily measurable fraction. This missing mass may be lost during the process of binding as energy in the form of heat or light, with the removed en… WebThe binding energy is −0.75 eV. h, Individual binding confirmation of CO2 on Cu2O (100) Cu termination.
