From: Defluorination and adsorption of tetrafluoroethylene (TFE) on TiO2(110) and Cr2O3(0001)

Energies [eV] required to dissociate one F from TFE in the presence of TiO2 (left panel) and Cr2O3 (right panel). Energies given for different configurations (reaction coordinate) relative to the corresponding reference geometries in the insets (E=0). Note that it requires 5.3 eV to dissociate one F from TFE in vacuum.
