High Stability, High Activity Pt/ITO Oxygen Reduction Electrocatalysts
Abstract
Sn-doped indium oxide (ITO) nanoparticles (NPs) were conceived as a high stability noncarbon support for Pt NPs, and the activity and stability of Pt/ITO for the oxygen reduction reaction (ORR) were probed. Sn was employed as the In(2)O(3) dopant to exploit the strong interaction between Sn and Pt that was previously reported to enhance the activity of Pt on Pt/SnO(2), while concomitantly avoiding the intrinsic stability limitations of SnO(2) and leveraging the high stability of bulk In(2)O(3) at ORR relevant potentials. The mass activity of Pt was extremely high on Pt/ITO, 621 ± 31 mA/mg(Pt), which far exceeded the 2015 DOE goal for Pt mass activity of 440 mA/mg(Pt). The enhanced ORR activity was linked to the faceting of the Pt NPs, which overwhelmingly consisted of Pt (111) facets. The stability of Pt/ITO was also very impressive, with the electrochemically active area unchanged and the Pt half wave potential shifting only 4 mV over 1000 potential cycles to 1.4 V vs RHE, a very harsh condition for ORR electrocatalysts where state-of-the-art Pt/C electrocatalysts typically show very poor stability.

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.
