V would be expected to outperform compared to current catalysts for the ORR. This shift would require the binding energy of the oxygen atoms to be reduced by the same amount across the whole potential range, which was previously done by tuning the nanoparticle size, composition or shape. Performing similar simulations using a universal potential such as MACE-MP-0 would allow for the exploration of these effects, along with external factors such as a support or a solvent, given that these more advanced forcefields retain reasonable accuracy. Additionally, going beyond the CHE approximation will be required to produce an accurate version of Figure . For example, our simulations do not account for electrochemical phenomena i.e. electric fields that arise due to the potential drop at the interface. Similarly, in the CHE framework, electrochemical adsorption is represented by a coupled electron-proton transfer, most likely misrepresenting any electrosorption valency phenomena normally involved in these adsorption process.
