This study applied a facile and green method to synthesize AgNPs in an aqueous medium using <em>Averrhoa bilimbi</em> fruit extract as a reducing and stabilizing agent. The formation of AgNPs was confirmed by using UV-visible spectroscopy, X-ray diffraction pattern (XRD), and High-resolution transmission electron microscopy (HRTEM). The synthesized AgNPs consist of face-centered cubic crystals and exhibit homogeneous spherical morphology with an average size of 11 nm. Heavy metals like mercury contamination in water and food pose global health risks, leading to disability issues, even at trace levels. Beside, H<small>₂</small>O<small>₂</small> is a reactive oxygen species. Thus, elevated H<small>₂</small>O<small>₂</small> levels can harm cell membranes, proteins, and DNA in aquatic creatures, resulting in oxidative stress that may affect physiological processes. Therefore, there is an urgent need for effective monitoring and prevention. The synthesized AgNPs were utilized as a colorimetric probe for the detection of mercury (Hg<small>²⁺</small>) ions in water at room temperature and found to be highly sensitive and selective with a limit of detection (LOD) of 1.58 μM and a limit of quantification (LOQ) of 5.27 μM. Furthermore, the detection of Hg<small>²⁺</small> was unaffected in the presence of other pertinent metal ions. The prepared AgNPs probe can also enable detection of Hg<small>²⁺</small> with the naked eye. In addition, the AgNPs probe was investigated for detecting Hg<small>²⁺</small> ions in real water samples, which offered satisfying recovery rates ranging from 90.60 ± 2.60 to 96.73 ± 2.83%, confirming the probe's practicability. The capping agent stabilized on the surface of AgNPs can effectively pre-concentrate Hg<small>²⁺</small> ions through the chemical interaction between AgNPs and Hg<small>²⁺</small> ions to form Ag–Hg amalgam. This leads to a decrease in the SPR peak from AgNPs. The interaction between Ag and Hg was investigated using synchrotron radiation-induced X-ray photoelectron spectroscopy (SR-XPS). In addition, the AgNPs probe effectively detected hydrogen peroxide (H<small>₂</small>O<small>₂</small>) in an aqueous medium with a LOD of 3.21 μM and LOQ of 10.70 μM.

In this work, efforts have been made to overcome these gaps and eventually enhance the performance of EDLCs <em>via</em> a cost-effective and eco-friendly approach. To fabricate these EDLCs, a bio-waste, namely, cotton-shell-derived activated carbons (ZnACs) (activated with ZnCl<small>₂</small>), was used in a mass ratio of 1 : 2 for cotton shell to ZnCl<small>₂</small>. This resulted in a large BET surface area of 2031 m<small>²</small> g<small>⁻¹</small> and a hierarchical porous structure, which contributed to faster diffusion of electrolyte ions. These two features ultimately resulted in a high specific capacitance of 247.82 F g<small>⁻¹</small> at a current density of 0.52 A g<small>⁻¹</small> of the cell with a porous polymer electrolyte (PPE) film made from polycaprolactone and poly (vinylidene fluoride-<em>co</em>-hexafluoropropylene), which offered the advantages of a wider potential window (∼7.22 V <em>vs.</em> Ag) and high conductivity (1.51 mS cm<small>⁻¹</small>). A comparison was then made with another cell using commercial activated carbon powder and the same PPE film. The ZnAC-based EDLC cells showed better performances, such as a high energy density (∼22.58 W h kg<small>⁻¹</small>) and high Coulombic efficiency (∼83.6%) without compromising the effective power density (∼0.42 kW kg<small>⁻¹</small>). EDLC cells exhibited only ∼3% capacitance fading at the end of 10 000 charge–discharge cycles. Thus, the incorporation of cotton shell-biowaste resulted in a two-way advantage of reducing environmental pollution caused by their large-scale burning practices and delivering substantial electrochemical performance, ultimately opening new avenues in the field of green energy technology.</p>","PeriodicalId":102,"journal":{"name":"RSC Advances","volume":" 13","pages":" 9787-9800"},"PeriodicalIF":3.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ra/d5ra00696a?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143740530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
