Product‐Reshaped Gas‐Phase Hydrodynamics Govern CO2 Electrolysis in Gas Diffusion Electrodes

Advanced Science, EarlyView.
In gas‐fed CO2${\rm CO}_2$ electrolysers, the gas phase is part of the electrochemical response. As gaseous products form, they change gas composition and flow, which in turn affects CO2${\rm CO}_2$ delivery and CO intermediate availability. This feedback changes the reaction environment needed for multicarbon formation, becoming unavoidable as ...

Cascade Desolvation and Conversion Reaction Driven by Self‐Tandem Catalysis for Wide‐Temperature Li‐S Batteries

Advanced Science, EarlyView.
A self‐tandem catalysis accelerating cascade reaction strategy is pioneered through constructing electron‐adjustable atom‐level Ce as the self‐tandem catalyst to lower energy barriers for fast Li+ desolvation and sequential sulfur conversion kinetics. The catalyzed cells operate effectively over a wide‐temperature range from 0 to ‐30 °C, delivering a ...

The Potential of Zero Charge: An Interfacial Descriptor Governing Hydrogen Evolution Reaction on Bulk Metal Electrodes

Advanced Science, EarlyView.
This work establishes a dual‐descriptor framework incorporating hydrogen adsorption free energy and potential of zero charge, constructing a corrected 3D HER volcano plot. It reveals that surface charge and interfacial proton concentration jointly govern activity, beyond conventional 2D thermodynamic scaling relations. ABSTRACT While the Sabatier‐based
