Electrochemically Induced Oxide‐to‐Hydroxide Transformation Enables Fast Proton Transport for Enhanced Hydrogen Evolution

open access: yesAdvanced Science, EarlyView.
An electrochemically induced transformation of polar MgO(111) into Mg(OH)2(001) creates a proton‐conductive hydroxide layer during hydrogen evolution. Operando synchrotron XRD and DFT reveal a low‐barrier Grotthuss proton‐hopping mechanism, establishing a feasible strategy for designing oxide‐hydroxide electrocatalysts with enhanced proton transport ...

CO2‐to‐CO Electrolysis in Pure Water at Ampere‐Level Current Density and 1000 h Stability via a Rapid‐Transport Fixed‐Charge Interface

open access: yesAdvanced Science, EarlyView.
CO2 reduction in pure water is enabled by a rapid‐transport fixed‐charge interface that couples nanochannels with a cationic microenvironment. This design eliminates the mass transport plateau, stabilizes key reaction intermediates, and suppresses the hydrogen evolution reaction, ultimately achieving ampere‐level current densities and stable operation ...

Orthogonal Design of Competing Deprotonation Process in Cation‐Mediated Ni(OH)2 for Achieving Industrial Level Biomass Electrooxidation

open access: yesAdvanced Science, EarlyView.
A Cu‐mediated Ni(OH)2 catalyst with orthogonal activity by precise valence engineering simultaneously accelerates rate‐determining aldehyde C─H activation in HMF oxidation and impedes O─H deprotonation in competing OER. This multi‐functional synergistic catalysis enables FDCA production at industrial‐level current densities without sacrificing FEFDCA ...

Unraveling the Power of Disorder: A Bioinspired Cuttlebone Structure With Superior Strength, Energy Absorption and Isotropy

open access: yesAdvanced Science, EarlyView.
Cuttlebone‐inspired architected metamaterials introduce controlled structural disorder to simultaneously enhance strength, energy absorption, and compressive stability. Tunable disorder suppresses shear anisotropy, outperforms periodic lattices, and establishes discrete randomness as a robust route to high‐performance lightweight mechanical ...

Optimizing Metal‐Perovskite Interfaces: Electronic and Transport Properties of Au‐Bromide Perovskites Contacts

open access: yesAdvanced Electronic Materials, EarlyView.
This study examines metal–perovskite interfaces in 2D (BA)2PbBr4 and (PEA)2PbBr4 using first‐principles and NEGF methods. It compares top‐ and edge‐contact configurations, revealing Schottky barriers in top contacts and ohmic behavior in edge contacts.
