Charge transport matters: The gas-phase response of the electrical conductivity, measured contact-free with the in situ microwave cavity perturbation technique, is studied for vanadium(III), (IV), and (V) phosphorus oxide catalysts under selective n-butane oxidation conditions. The deduced surface–bulk charge transport properties of the samples provide a fingerprint for the activity and selectivity in the demanding selective oxidation that requires a 14 e− transfer per catalytic cycle.
