Oxophilicity‐Driven Potential Window Engineering Enables Scalable and Low‐Emission Paired Electrosynthesis on Asymmetric CuOx@Ag Platform

Carbon and Hydrogen, EarlyView.
An asymmetric CuOx@Ag electrocatalyst platform enables paired electrochemical valorization of glycerol and 4‐nitrophenol, while effectively decoupling both half‐reactions from OER and HER. Ag‐mediated surface engineering expands the potential window and boosts reaction selectivity, achieving > 90% Faradaic efficiencies at both electrodes.

Regulating Interfacial Hydrogen‐Bonding Connectivity by Oxygen Vacancies‐Driven [Fe(CN)6]3− Coordination for Boosting Hydrogen Peroxide Electrosynthesis

Carbon Energy, EarlyView.
ABSTRACT The inherent hydroxide‐rich (OH⁻) environment in alkaline media facilitates the two‐electron oxygen reduction reaction (2e−ORR). However, the strong interaction between alkali metal cations and solvated water molecules significantly reduces the connectivity of the hydrogen bond network within the alkaline electric double layer, thereby ...

Modulating Metal–Oxygen Bond Energy by Valence State Engineering in 2D High Entropy Oxides for Enhanced Water Electrolysis

Carbon Energy, EarlyView.
The competitive redox equilibrium among different elements in 2D HEO is regulated through temperature‐controlled pyrolysis of 2D HEHO, obtaining 2D HEO with a continuously adjustable valence state of Fe, Ni, Mo, Ru, and V elements, which modulate the strength of the metal–O bond and activate the LOM‐OVSM for OER.

Synergistic Fe–Si Dual‐Site Pathway Engineering in Biomass‐Derived Carbon Matrix for High‐Performance Oxygen Reduction Reaction

Carbon Energy, EarlyView.
We report a dual‐atomic Si–Fe–N–C catalyst synthesized from nitrogen‐rich pinecones and an Fe porphyrin precursor. The inherent Si and N in pinecones form a porous Si–N–C framework that stabilizes Fe atoms during pyrolysis, yielding robust Si–Fe dual sites.
