Chemical bath deposition (CBD) is a facile technique to coat the substrate with thin and uniform coating of material unique morphology. Herein, CBD method was adopted fabricate nickel sulfide/cobalt sulfide (NiS/CoS) electrodes for supercapattery application. The NiS/CoS were fabricated at different times study evolution morphology respect time. Deposition time crucial factor in regulating growth kinetics active attain desired energy storage applications. XRD X‐ray photoelectron spectroscopy (XPS) analysis verified nanostructures on foam (NF) surface. Based field emission scanning electron microscope (FESEM) micrographs, it evident that 2.5 h ideal maximum coverage spherical thread‐like resembling pollen grains. Correlatedly, NiS/CoS‐2.5 electrode showed highest specific capacity 2.60 C cm −2 2.0 mA current density. optimized coupled activated carbon (AC) NiS/CoS‐2.5//PVA + KOH//AC supercapattery, which sustained 90% initial after 2000 continuous cycles 4.0 . This portrays prospects as simple yet reliable approach developing good

Enhanced Roughness of Graphene Foam for Optimizing Surface Active Copper With Efficient Electrochemical Detection of Nitrate

Advanced Sustainable Systems, Journal Year: 2025, Volume and Issue: unknown

Published: April 13, 2025

Abstract In light of the growing concern over nitrate pollution, developing convenient and efficient electrochemical sensors for ions is crucial enhancing monitoring drinking water food safety. To improve sensitivity stability copper‐based electrodes detection, ultra‐high conductivity graphene foam developed by group utilized as a supporting electrode copper. By increasing surface roughness foam, its binding interaction with copper enhanced, which significantly improved electron transfer efficiency in composite during detection. Concretely, roughened promotes formation dense layer higher content Cu(OH) 2 well oxygen defects, enhances adsorption further improves detection sensitivity. The resulting achieves an impressive limit 1.78 µ m . This study demonstrates that optimizing can enhance performance electrodes, offering valuable insights design development next‐generation, highly active electrodes.
