Its oxygen acceptor and donor properties have been evaluated by showing the effect of admixed α-Sb2O4, which is a good oxygen donor able to increase the selectivity of an acceptor phase, and of MoO3 which generally acts as a good oxygen acceptor, namely carries all the functions necessary for oxidation, but has only a weak ability to dissociate oxygen.
It is concluded based on experimental and theoretical evidence that four-electron O2 reduction on Pt electrodes at low overpotentials requires a special site characterized by a relatively small ratio of OH to H2O adsorption bond strengths and or a higher activation energy for OH ads) formation by reaction (i), as well as a weak ability to adsorb anions.
