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 ...

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.

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,
