Dual‐Functional Membranes With Interfacial MXene/PFSA Nanoarchitectures for Low Hydrogen Permeation in Water Electrolysis and Reduced Vanadium Ion Crossover in Flow Batteries

open access: yesAdvanced Science, EarlyView.
A PFSA/MXene composite membrane is developed for both PEMWE and VRFB applications. MXene incorporation simultaneously enhances proton conductivity and suppresses hydrogen/vanadium crossover. The interaction between MXene functional groups and PFSA's –SO3H reduces the proton diffusion barrier via hydrogen‐bonding networks, while the disordered ...

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

open access: yesAdvanced 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 ...

31P Solid‐State NMR‐Enabled Development of a Pt/Aluminum Tripolyphosphate Catalyst for Selective C─O Bond Hydrogenolysis of Phenols

open access: yesAngewandte Chemie, EarlyView.
31P solid‐state nuclear magnetic resonance analysis revealed the presence of aluminum tripolyphosphate on the surface of a platinum/aluminum condensed phosphate mixture (ACPM) catalyst. This finding led to the development of a Pt/aluminum tripolyphosphate (Pt/ATPP) catalyst for the selective hydrogenolysis of phenols to arenes.
