Vacancy‐Driven Ni Exsolution in Prussian Blue Analogues Creates Cooperative Defect–Metal Sites for Alkaline Hydrogen Evolution

Advanced Science, EarlyView.
Multimetal Prussian blue analogues (PBAs) are converted by low‐temperature Ar annealing into a cavity/CN‐vacancy architecture that triggers in situ Ni exsolution, creating dense Ni‐PBA interfacial motifs. These motifs optimize water dissociation and H* adsorption in alkaline media, delivering markedly accelerated HER kinetics and long‐term stability ...

Laser Preset of MnOx Layer on High‐Entropy Alloy Surface for Ampere‐Level Ultra‐Stable OER Performance

Advanced Science, EarlyView.
3D printing enables a high entropy alloy‐derived, in situ formed MnOx overlayer that suppresses oxidation–reconstruction and mitigates anodic dissolution, while enhancing electrolyte wetting and bubble release to accelerate interfacial mass transport and OER kinetics.

Bipolar Palladium Membrane Enabling Crossover‐Free Selective Proton Transport

Advanced Science, EarlyView.
This study introduces a crossover‐free bipolar palladium membrane that transports protons selectively via reversible Pd/PdHx absorption–desorption and lattice hydrogen diffusion, overcoming the conductivity–selectivity trade‐off of polymer membranes. It enables water‐fed Li‐mediated ammonia synthesis, achieving 51% Faradaic efficiency and stable 12 h ...

OER bringt’s?

, 2023
In dieser Reflexion wird das Thema „OER an Hochschulen“ näher beleuchtet und besonders die Vorteile hervorgehoben. Durch die Ausbildung zum/zur OER-Praktiker:in haben die Autor:innen Vor- und Nachteile kennengelernt, sich angeschaut, wo OER-Material zu finden ist und wie eigene OER-Materialien erstellt werden können.

In Situ Reconstructed Crystalline–Amorphous CuNi Nanotubes Unifying Activity and Stability for Oxygen Evolution

Advanced Science, EarlyView.
Controlled electrochemical reconstruction creates a crystalline–amorphous CuNi nanotube that unifies catalytic activity and durability for alkaline oxygen evolution. The conductive metallic core and active amorphous oxide shell work synergistically to deliver low overpotential and exceptional stability exceeding 1000 h, offering a new strategy for ...

Real‐Time Investigation of Interfacial Evolution in Electrochemical Energy Storage Systems via EQCM

Advanced Science, EarlyView.
Understanding the electrode/electrolyte interface (EEI) is crucial for supercapacitors and batteries. EQCM, by enabling real‐time monitoring of mass changes during charge–discharge cycles, has evolved into a vital method for analysis of EEI. It provides important insights into charge‐storage mechanisms, electrode structural evolution, ion‐transfer ...
