Molecular Electrocatalysis Coupled With a Palladium Membrane Reactor Affords Selective Nitrogen Reduction

open access: yesAdvanced Science, EarlyView.
A palladium membrane reactor delivers active hydrogen to homogeneous nickel terpyridine catalysts, which then selectively hydrogenate dinitrogen to ammonia. ABSTRACT Ammonia production is a cornerstone of modern industry and society, yet the conventional Haber–Bosch process accounts for nearly 2% of the global CO2 emissions. A promising and potentially

Wafer‐Scale Dendritic Nanoporous Platinum Films for Neural Electrodes

open access: yesAdvanced Science, EarlyView.
Wafer‐scale dendritic nanoporous platinum films with intrinsic nanoscale porosity are synthesized by suraface‐confined wet chemistry and transferred onto flexible substrates to create tissue‐conformal neural electrodes. The ultrathin films combine mechanical flexibility with electrochemical stability, enabling low‐impedance, high‐capacitance interfaces

Porcupine‐Quill‐Inspired Shape‐Morphing Biointerfaces Disassemble Biofilms

open access: yesAdvanced Science, EarlyView.
A porcupine‐spine‐inspired dynamic offensive bio‐interface is developed for active biofilm disassembly. By coupling electrically driven nano‐dagger penetration with light‐triggered ROS generation, the surface overcomes the passive limitations of conventional mechano‐bactericidal topographies, achieving near‐complete biofilm eradication, strong ...

Hydrogen Production from Ammonia Electrochemical Cracking

open access: yesAdvanced Science, EarlyView.
NH3 electrochemical cracking (e‐cracking) is a complementary technique to centralized thermal cracking for releasing H2 from NH3. In this article, we review recent advances in catalyst development for these cracking techniques and conduct a techno‐economic analysis (TEA) to evaluate the economic feasibility of e‐cracking.

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 ...
