Spin‐Selective Oxygen Evolution in Chiral Molecule‐Intercalated Layered Double Hydroxides

Advanced Science, EarlyView.
This hybrid electrocatalyst utilizes chiral phenylalanine intercalation within layered double hydroxides to boost oxygen evolution. Acting as a spin filter via the chiral‐induced spin selectivity effect, the material directs electron transfer along a lower‐energy pathway.

Study on the Reaction Mechanism of RuOx and Its Enhanced Hydrogen Evolution Reaction Activity

Advanced Science, EarlyView.
In situ Raman spectroscopy and DFT calculations reveal that, prior to the onset of HER, the surface of RuOx undergoes reversible reduction and structural reconstruction. The resulting Ru(II)O/Ru(IV)O2 configuration is identified as the true catalytically active species.

Electrocatalytic Coupling Conversion of Methane by Dual‐Site Control in Nickel Oxyhydroxide

Advanced Science, EarlyView.
Electrocatalytic coupling conversion of methane (CH4) is accomplished on the nickel oxyhydroxide (NiOOH), wherein the Ni─O dual‐site is triggered via the proper electronic interaction, synergistically promoting the C─H activation and C─C formation, enabling a selective and efficient C2 product generation route under ambient conditions. ABSTRACT Methane

Reconstruction of Ultrafine MnS‐Induced Vacancy‐Rich Co9S6.29 Precatalysts in Mesoporous S‐Doped N‐Rich Hollow Carbon Nanotubes Enables Dynamic O‐Vacancy Cycling for High‐Performance Zn‐Air Batteries

Advanced Science, EarlyView.
We develop vacancy‐rich Co9S6.29 precatalysts formed via ultrafine MnS‐induced lattice distortion in mesoporous S‐doped N‐rich hollow carbon nanotubes (CM@SNHCTs). This CM@SNHCT precatalyst is reconstructed into catalytically‐active cathode phases that enable efficient oxygen reduction/evolution reactions (ORR/OER) through dynamic O‐vacancy formation ...
