COMPUTATIONALMETHODS E Cl*M1 Cl*M2 Cl-(aq) RCl-M Figure 2.2: A qualitative description of the relationship between the reaction en- ergy and the transition state energy for adsorption of Cl– on two different surfaces, M1 and M2. M2 binds the Cl* adsorbate more strongly than M1. ∆Ei indicate the reaction energies and ∆Ei the transition state energies. The dotted lines indicate the energies of the initial and final states as a function of the Cl-M distance, and the fully drawn lines indicate the actual reaction paths. The transition state is found at the avoided crossing between the initial state and the final state. way previously described). This is not unexpected, as the energy of the transition state structure is also affected by the bonding to the surface in the same way as the energies of the intermediates, as is indicated in Figure 2.2[109]. The figure gives a qualitative description of the relationship between the reaction free energy of Cl– adsorption on two different surfaces M1 and M2, where M2 binds the Cl* adsorbate more strongly. As M2 binds the Cl* adsorbate more strongly, the re- action energy is more negative, which in turn results in a lower transition state energy. While BEP relations have been found primarily for nonelectrochemical heterogeneous reactions, similar relationships have also been found for electrocat- alytic reactions[193]. It is assumed that BEP-relations also exist for the OER and ClER on rutile oxides, but this has not been verified thus far. 2.4.2 Sabatier analysis As described in the previous section, the rates of heterogeneously catalyzed reac- tions, including electrocatalytic reactions, are controlled by reaction energies.
