Various metal (In, Ti, Nb, W, Sn, Mo, and Ta) oxides have been commonly used as metal supports in long-running reactions.
“For decades, various metal (In, Ti, Nb, W, Sn, Mo, and Ta) oxides have been commonly used as metal supports in long-running reactions.”

The catalytic potency of Pt-based nanocrystallites is slowly reduced through the migration, coalescence, and aggregation of the Pt metal during the electrochemical process.
“Thus, the catalytic potency of Pt-based nanocrystallites is slowly reduced through the migration, coalescence, and aggregation of the Pt metal during the electrochemical process.”

At a higher potential (E > 1.5 vs RHE), accelerated COR kinetics lead to agglomeration and finally detachment of the Pt NPs from the support.
“Even at a higher potential (E > 1.5 vs RHE), accelerated COR kinetics were observed that lead to agglomeration and, finally, detachment of the Pt NPs from the support.”

In proton-exchange membrane fuel cells, the carbon support undergoes the carbon oxidation reaction (COR) at a potential E > 0.2 V vs RHE followed by steady continuous dissolution of the metal support at the cathode.
“For instance, in proton-exchange membrane fuel cells, the carbon support undergoes the thermodynamically favorable carbon oxidation reaction (COR) at a potential E > 0.2 V vs a reversible hydrogen electrode (RHE) followed by the steady continuous dissolution of the metal support at the cathode.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
