Surface‐Selective Pt Enrichment for Stabilizing Ultrathin 2D PtCu Nanosheets Toward Durable Oxygen Reduction

Advanced Science, EarlyView.
Ultrathin 2D alloy nanosheet catalysts could offer exceptional catalytic activity but suffer from severe structural instability. Here, a surface‐selective Pt enrichment strategy via galvanic replacement effectively stabilizes PtCu Nanosheets while preserving their ∼ 1 nm thickness and (111) facets.

Surface Coordination‐Dependent Oxygen Evolution Pathways in Rutile IrO2

Advanced Science, EarlyView.
Epitaxial rutile IrO2 surfaces with crystallographically distinct orientations reveal a strong dependence of oxygen evolution reactivity on surface atomic coordination. The (110) and (101) surfaces exhibit O‐rich electronic character and an energetic preference for the quadruple oxygen coupling mechanism (QOCM), whereas the (001) surface shows more Ir ...

Surface‐State‐Driven Selectivity of Electrocatalytic Glucose Oxidation: Metallic Au, Au─OH, and CuO

Advanced Science, EarlyView.
In the electrochemical oxidation of glucose, whether the pyranose ring opens upon adsorption decides the reaction pathway: ring opening on metallic Au yields gluconic acid, gluconolactone formation on Au─OH leads to glucaric acid, and C─C cleavage on CuO gives formic acid. Surface state thus governs product selectivity.

Gd‐Mediated Spin‐State Modulation of Co Sites Enhances Oxygen Electrocatalysis in Zn‐Air Battery

Advanced Science, EarlyView.
The Gd‐mediated spin‐state modulation strategy was proposed to enhance electrocatalytic performance of Co sites towards oxygen reduction reaction. The Gd incorporation modulates the local electronic structure of Co centers by inducing pronounced spin splitting and orbital‐selective spin polarization, which optimizes the adsorption of oxygen‐containing ...
