O 2 Reduction on an Ink‐Type Rotating Disk Electrode Using Pt Supported on High‐Area Carbons
Abstract
The kinetics of O 2 reduction has been examined on an ink‐type electrode made with Pt supported on high‐area carbon. Electrocatalysts with 5–40 mass % of Pt on Black Pearls, Vulcan XC‐72, and Shawinigan acetylene black carbons were used. Experiments were performed in 0.1 M solutions of H 2 SO 4 , H 3 PO 4 , HClO 4 , and NaOH. Kinetic parameters of O 2 reduction were found to be similar as on a smooth Pt surface. No influence of the type of carbon was observed. The mass activity of O 2 reduction was independent of Pt loading at low currents, but at high currents the mass activity decreased with an increase in Pt loading. It is suggested that mass‐transfer limitations are responsible for the different influence of Pt loading on mass activity at low and high currents. Reproducibility of the measurements on the ink electrode was satisfactory, and it is recommended for investigations of dispersed electrocatalysts.

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.
