This study has highlighted a modest and straightforward approach for the preparation of 3-aminopropyl trimethoxysilane (APTMS)-functionalized graphene oxide (GO-APTMS) and its composites with cobalt (GO-APTMS/Co) and nickel (GO-APTMS/Ni). The prepared catalysts were utilized for the oxygen evolution reaction (OER) in a basic medium (0.1 M KOH). The prepared composites, GO-APTMS/Ni and GO-APTMS/Co, are characterized using spectroscopic methods, such as Fourier transform infrared (FT-IR), ultraviolet (UV-vis), powder X-ray diffraction (P-XRD), FT-Raman, X-ray photoelectron spectroscopy (XPS), and energy dispersive X-ray spectroscopy (EDS). It was also characterized with transmission electron microscopy (TEM) and selected area electron diffraction (SAED). The nanocomposites GO-APTMS/Ni and GO-APTMS/Co are deposited on the surface of a glassy carbon (GC) electrode to study their electrochemical behavior. It is observed that GC modified GO-APTMS/Ni (GC/GO-APTMS/Ni) and GO-APTMS/Co (GC/GO-APTMS/Co) have efficient OER activity. The Tafel slopes of nanocomposite materials GC/GO-APTMS-Co and GC/GO-APTMS-Ni are 74 and 183 mV/dec, respectively, in a 0.1 M KOH solution. GC/GO-APTMS/Co and GC/GO-APTMS/Ni exhibit remarkable OER activity with low onset potentials of 1.63 and 1.65 V, respectively, with satisfactory operational stability. This indicates that GC/GO-APTMS-Co could be a promising, cost-effective electrode material for OER. This study demonstrates a novel way of creating an active nanocomposite catalyst for OER in alkaline media. Hence, it could be a suitable alternative for the replacement of a high-cost electrocatalyst in the fuel cells, metal-air batteries, water electrolyzers, etc.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":535,"journal":{"name":"Electrocatalysis","volume":"17 4","pages":"774 - 789"},"PeriodicalIF":3.2,"publicationDate":"2026-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148342911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reducing and stabilizing properties of plant-derived organic constituents enable the environmentally friendly and cost-effective synthesis of ZnO–Ag nanoparticles.

Converting nitrogen in wastewater into ammonia is an alternative to the Haber-Bosch process, which constitutes an effective and economical method for addressing nitrate contamination in source waters. This process simultaneously facilitates the reclamation of nitrogen as a renewable and promising energy resource. This approach not only decreases dependence on energy-consuming procedures but is also environmentally friendly. Copper-based electrocatalysts for the nitrogen/nitrate reduction reaction (NRR) have been widely studied, yet a comprehensive understanding of the relationships between their preparation, characterization, and catalytic activity remains incomplete. In this review, we aim to provide a structured summary of synthetic approaches for Cu-based electrodes using both physical and chemical methods, highlighting the structure–activity correlations between synthesis strategies and catalyst performance. We also present a thorough overview of advanced characterization techniques, including structural, morphological, compositional, electrochemical, and in situ/operando studies, to identify active sites, reaction intermediates, and degradation pathways. The electrocatalytic performance of Cu-based electrodes in NRR is critically analyzed and compared, with emphasis on the effects of morphology, surface composition, electrolyte selection, and pH on activity and selectivity. Methods for quantifying ammonia, such as colorimetry, NMR, GC, and ion chromatography, are reviewed to ensure benchmarking and reproducibility. Despite these advances, practical application remains limited due to challenges such as the trade-off between selectivity and activity, catalytic deactivation, and competition from the hydrogen evolution reaction (HER). This work aims to provide a consistent and rational framework for screening Cu-based systems toward highly efficient and cost-effective ammonia electrosynthesis.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":535,"journal":{"name":"Electrocatalysis","volume":"17 4","pages":"584 - 614"},"PeriodicalIF":3.2,"publicationDate":"2026-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148342976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
