ZrCo3B2 and HfCo3B2 Electrodes Go on Stage for Oxygen Evolution Reaction

Advanced Science, EarlyView.
The intermetallic compounds ZrCo3B2 and HfCo3B2 with distinctive chemical bonding features are excellent OER precursors, restructuring into OER‐active electrocatalysts delivering significantly high OER activities compared to the elemental Co, which is obvious from their lower onset potentials and increased obtained current densities.

Spin-dependent electrocatalysis

National Science Review
ABSTRACT The shift towards sustainable energy requires efficient electrochemical conversion technologies, emphasizing the crucial need for robust electrocatalyst design. Recent findings reveal that the efficiency of some electrocatalytic reactions is spin-dependent, with spin configuration dictating performance.

Controlled Lattice Distortion and Lattice‐Strain‐Engineered CoCuIr Alloy toward Preferential Chlorine Tolerant Direct Seawater Electrolysis

Advanced Science, EarlyView.
A lattice‐strain‐engineered Co0.28Cu0.67Ir0.05 trimetallic alloy nanoparticle electrocatalyst is rationally designed for efficient alkaline seawater electrolysis. Larger Ir atoms in the CoCu lattice modulate the local coordination environment, generating compressive lattice strain and highly active catalytic sites.

Co‐Ligand‐Induced Electronic Modulation Controls Substrate Adsorption and Selectivity in Biomass Electrooxidation

Advanced Science, EarlyView.
A molecular design strategy is reported that introduces distinct anionic co‐ligands into Cu‐based catalysts to modulate the electronic density of the metal center and, consequently, its interaction with both OHads and HMF. The work establishes co‐ligand engineering as an effective strategy for precise interfacial adsorption control in electrocatalysis,

Nanocluster‐Assisted OH Ligand Modification Optimizes Activity and Stability of Fe‐N‐C Catalysts

Advanced Science, EarlyView.
A nanocluster‐assisted ligand engineering stabilizes OH‐modified FeN4 active sites through strong electronic coupling between isolated Fe atoms and adjacent nanoclusters. This synergy optimizes oxygen‐intermediate adsorption, lowers ORR energy barriers, and breaks the conventional activity–stability trade‐off, enabling high ORR activity, exceptional ...

V2CTx MXene as a Sacrificial Promoter for NiFe Catalyst for Anion Exchange Membrane Electrolyzers

Advanced Science
Nickel‐iron layered double hydroxides (NiFe‐LDH) show excellent activity, their poor conductivity limits practical implementation in electrolysers. Previous reports have shown that combining nickel‐iron layered double hydroxide (NiFe‐LDH) materials with ...

Interfacial Tandem Catalysis Over a CuSn(OH)6/Co Heterostructure Enables Efficient Electroreduction of Nitrate to Ammonia

Advanced Science, EarlyView.
Interfacial tandem catalysis is developed for efficient electrochemical reduction of NO3− to NH3 over a CuSn(OH)6/Co heterostructure. CuSn(OH)6 accelerates the rate‐determining NO3−‐to‐*NO2 conversion, whereas Co promotes H2O dissociation to enhance *H supply for the rapid hydrogenation of *NO2 intermediate to NH3.
