Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Fe0.33-Ni0.67-MOF is the optimal composition, reaching about 100% NO conversion at low temperature and zero N2O yield above 225 C under CO-SCR conditions.
Caveat: Catalytic performance is not an electrical-transport or thermoelectric measurement.
9917, 9925 · Catalytic reduction of NO by CO; Conclusions · Figures 1-3 · Linked to 3 structured results
Despite a statement that higher Ni3+ abundance can benefit electronic conduction transport, the paper does not report first-hand electrical transport, thermoelectric, or electrochemical measurements for the MOF samples.
Caveat: This extraction therefore records spectroscopy/catalysis evidence only and leaves electrical_transport and thermoelectric measurements absent.

Fe modification increases BET surface area, promotes longer rodlike crystal growth along the (001) direction, raises Ni3+ concentration, and increases surface oxygen vacancy indicators, which the authors connect to enhanced low-temperature CO-SCR activity.
Caveat: The structure-property link is mechanistic interpretation from characterisation and catalysis correlations, not direct transport measurement.
9925 · Conclusions · Linked to 4 structured results
A special Fe-Ov-Ni surface synergistic oxygen-vacancy structure is proposed to weaken N-O bonds, promote nitrate/nitrite intermediates, and improve low-temperature NO reduction.
Caveat: The Fe-Ov-Ni motif is a proposed mechanism based on XPS and in situ FT-IR observations rather than a directly solved atomistic structure.
9925 · Reaction mechanism · Figure 13 · Linked to 3 structured results
The authors propose that Fe/Ni redox equilibrium and Fe-O-Ni mixed bonds modify the local electronic structure of Ni centres and accelerate electronic transfer during SCR reactions.
Caveat: Electronic transfer is inferred from XPS/H2-TPR and reaction chemistry; no conductivity, Seebeck, Hall, or device transport data were reported.
