Ferroelectric Catalysts in the Hydrogen Evolution Reaction: A Perspective

Advanced Science, EarlyView.
This perspective summarizes recent advances in ferroelectric (FE) catalysts for the hydrogen evolution reaction (HER). It first introduces HER fundamentals and FE mechanisms, then classifies FE catalysts into single‐phase, single‐atom‐modified, heterostructured, and other engineered types, with representative examples.

Interfacial Electric Field Engineering of High‐Entropy Heterostructures Triggering Self‐Limiting Reconstruction for Industrial‐Scale Electrocatalysis

Advanced Science, EarlyView.
An interfacial electric field engineering strategy is proposed to trigger the self‐limiting surface reconstruction of high‐entropy heterostructures. Driven by this built‐in field, the controlled sacrificial leaching of W evolves a robust active layer, enabling exceptional oxygen evolution performance and ultrastability at ampere‐level current densities

Stabilising the Lattice Oxygen Oxidation Mechanism Through Iridium Single Atoms in Chromium‐Doped Cobalt Iron Layered Double Hydroxides

Advanced Science, EarlyView.
Iridium single atoms and Cr doping synergistically activate and stabilise the lattice oxygen oxidation mechanism in CoFe layered double hydroxides. Electronic modulation enhances metal–oxygen covalency, suppresses over‐oxidation, and enables durable oxygen evolution, delivering high‐performance anion exchange membrane water electrolysis with ...

Electrocatalytic CO2 Reduction over Sn‐Cu Bimetallic Catalysts Synthesized via an Amalgamated Lithium Metal Method

Advanced Science, EarlyView.
An amalgamated lithium metal method enables systematic control of Sn–Cu active‐site dimensions from isolated atoms to nanocrystallites. Increasing the metal loading shifts CO2 electroreduction selectivity from acetaldehyde on highly dispersed Sn–Cu sites to formate on Sn‐rich crystallites, revealing how bimetallic dispersion and local coordination ...

Dynamic Cobalt Leaching‐Redeposition Equilibrium in Co9S8/Co‐Ni3S2 Electrocatalysts Boosts Oxygen Evolution Activity

Advanced Science, EarlyView.
Reconstruction of a Co9S8/Co‐Ni3S2 electrocatalyst stabilizes via a leaching‐redeposition dynamic equilibrium of metal ions. Interestingly, the Co‐ion leaching and redeposition play a crucial role in boosting oxygen evolution performance. This endogenous self‐repair cycle continuously offers active sites, allowing the catalyst to maintain superior OER ...
