IPO-XRD captures the spatial transition from oxidized molybdenum phases (Al2(MoO4)3 and Mo-suboxides) to reduced MoO2, directly linked to the depletion of gas-phase oxygen. Excellent agreement between iso-potential measurements and direct reactor measurements at a synchrotron confirms the validity of the concept, while additional experiments on a laboratory diffractometer demonstrate its broader applicability.enhttps://creativecommons.org/publicdomain/zero/1.0/Iso potential operando spectoscopyHeterogeneous CatalysisX-ray diffractionProfile reactorCatalyst structural dynamicsNatural Sciences and Mathematics::541: Physical; Theoretical::541.3: Physical ChemistryDatasethttps://doi.org/10.15480/882.1694010.15480/882.16940Horn, RaimundRaimundHorn
