The immobilization of palladium nanoparticles (Pd NPs) on stainless-steel mesh is described in two short steps via deposition of graphene oxide (GO) on the stainless-steel mesh (mesh-GO) by electrophoretic deposition (EPD), preparation of Pd NPs using laser ablation in liquids (LAL) and finally the immobilization of Pd NPs on the mesh-GO by immersion in a Pd NP colloidal solution. The novel, efficient and reusable mesh-GO/Pd catalyst was characterized by various techniques such as SEM, EDS, UV-Vis and FT-IR spectroscopy and its catalytic activity was investigated for the Suzuki–Miyaura and Stille coupling reactions in ethanolic water.

Radio frequency plasma is one of the means to modify the polymer surface namely in the activation of polypropylene membranes (PPM) with O₂ plasma. Activated membranes were deposited with TiO₂ nanoparticles by the dip coating method and the bare sample and modified sample (PPM5-TiO₂) were irradiated by UV lamps for 20–120 min. Characterization techniques such as X-ray diffraction (XRD), Attenuated total reflection technique- Fourier transform infrared spectroscopy (ATR-FTIR), Thermogravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS), Scanning electron microscope (SEM) and water contact angle (WCA) measurements were applied to study the alteration of ensuing membrane surface properties which shows the nanoparticles on the sample surface including the presence of Ti on PPM. The WCA decreased from 135° (PPM) to 90° (PPM5-TiO₂) and after UV irradiation, the WCA of PPM5-TiO₂ diminished from 90° to 40°.

The electrochemical reduction of nitrogen species offers a sustainable route to mitigate environmental nitrogen pollution while enabling the production of value‐added chemicals such as ammonia, hydroxylamine, and C─N coupled organonitrogen compounds. However, the practical implementation of conventional potentiostatic methods is hindered by poor product selectivity and competing hydrogen evolution. Pulsed electrolysis has emerged as a transformative strategy to address these challenges by synchronizing catalyst surface dynamics with local microenvironmental changes and reaction kinetics. This mini‐review highlights recent advances in pulsed electrolysis for nitrogen species reduction, with a particular focus on how dynamic potentials influence electrocatalyst behavior and the surrounding reaction environment. Key mechanistic insights and cutting‐edge research findings are discussed, followed by an outlook on established systems and future directions toward scalable and energy‐efficient nitrogen activation.

Zusammenfassung: Die elektrochemische Reduktion von Stickstoffverbindungen bietet einen nachhaltigen Ansatz zur Minderung der Stickstoffbelastung der Umwelt und ermöglicht gleichzeitig die Herstellung wertvoller Chemikalien wie Ammoniak, Hydroxylamin und C–N‐gekoppelter organischer Stickstoffverbindungen. Die praktische Umsetzung herkömmlicher potentiostatischer Verfahren wird jedoch durch eine geringe Produktselektivität und die konkurrierende Wasserstoffentwicklung behindert. Die gepulste Elektrolyse hat sich als transformative Strategie erwiesen, um diese Herausforderungen zu bewältigen, indem sie die Dynamik der Katalysatoroberfläche mit lokalen mikroumweltbedingten Veränderungen und der Reaktionskinetik synchronisiert. Diese Mini‐Übersicht beleuchtet die jüngsten Fortschritte in der gepulsten Elektrolyse zur Reduktion von Stickstoffverbindungen, mit besonderem Fokus darauf, wie dynamische Potenziale das Verhalten von Elektrokatalysatoren und die Reaktionsumgebung beeinflussen. Wichtige mechanistische Erkenntnisse und innovative Forschungsergebnisse werden diskutiert, gefolgt von einem Ausblick auf etablierte Systeme und zukünftige Entwicklungen hin zu einer skalierbaren und energieeffizienten Stickstoffaktivierung.
