The formation of oxide layers at these potentials influences the reaction kinetics via siteblocking, and possible modification of the thermodynamic landscape. We seek to characterize the exact nature of both influences by conducting further investigations. Via the two fittings performed in Figure and Figure linking the potential to ∆ ḠO is possible. Following established methodologies from previous studies, we construct a volcano plot for the oxidized nanoparticles, assuming that the scaling relations hold for our oxidized catalysts and given by Equations 4a and 4b.
