Defect‐Rich Porous Palladium Metallene for Enhanced Alkaline Oxygen Reduction Electrocatalysis
Abstract
Metallene with fantastic physicochemical properties is considered as a potential candidate for oxygen reduction reaction (ORR). Controlling the morphology and structure of metallene can provide a great opportunity to improve its catalytic performance. Herein, defect‐rich ultrathin porous Pd metallene (a sub‐nanometer and curved metal nanosheet) is developed by facile wet‐chemistry strategy for efficient and stable ORR electrocatalysis in alkaline electrolyte. The defect‐rich porous Pd metallene provides abundant highly active sites and vacancy defects, showing superior ORR activity of 0.892 A mg Pd−1 at 0.9 V vs. the reversible hydrogen electrode. The mass activity is 5.1 and 16.8 times higher than those of commercial Pt/C and Pd/C, respectively, and maintains well after 5000 cycles. The strain effect and tunable electronic structure derived from highly curved sub‐nanometer nanosheet morphology contribute to the excellent ORR performance by the optimization of oxygen binding ability on Pd. The superior catalytic performance of Pd metallene may open an avenue to design other metallene materials for various fields.

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.
