Pt NPs Supported on CeO2/C as Electrocatalysts for Oxygen Reduction Reaction: Novel Physicochemical Insights on the Synthesis and on the Improved Activity and Stability

open access: yesSmall, Volume 21, Issue 25, June 26, 2025.
The effect of CeO2 on the Pt nanoparticles nucleation and growth and on the activity versus the oxygen reduction reaction was studied by in situ synchrotron wide‐angle X‐ray total scattering. The most active catalyst (MA = 423 A g−1; SA = 446 µA cm−2) shows greater stability than the commercial benchmark as demonstrated by accelerated stress tests at ...

Commensurate, Incommensurate, and Reconstructed Structures of Multilayer Transition Metal Dichalcogenide and Their Applications

open access: yesSmall, EarlyView.
This review categorizes ML‐TMDs into commensurate and incommensurate structures and examines their effects on electronic band structures, optical responses, ferroelectricity, and the anomalous Hall effect. It discusses synthetic methods, such as mechanical stacking, chemical vapor deposition (CVD), interfacial epitaxy, and hypotaxy, and introduces the ...

Untangling the Mechanisms in Magneto‐Electrocatalytic Oxygen Evolution

open access: yesSmall, EarlyView.
Magnetic fields can enhance the oxygen evolution reaction in electrocatalytic water‐splitting for green‐H2. Yet, commercialization cannot be realized until the underlying magneto‐electric mechanisms are understood. This work uses reactor orientation to untangle these mechanisms. Lorentz force is shown to control metallic plates, while spin‐polarization

Metal–Organic Frameworks for the Capture of Chlorinated Volatile Organic Compounds: A Case Study on Perchloroethylene

open access: yesSmall, EarlyView.
Indoor air pollution from chlorinated volatile organic compounds like perchloroethylene (PCE) poses health risks. Conventional abatement methods are energy‐intensive, but adsorption‐based techniques using metal–organic frameworks (MOFs) offer eco‐friendly alternatives.
