Due to its advantageous features, the electrochemical technique has garnered considerable attention in detecting 4-nitrophenol (4-NP). And modified materials of such working electrode significantly influence sensitivity sensor. In this investigation, a sensitive and selective sensor for 4-NP real water samples was developed by using spherical onion-like carbon (OLC) as new material modification. By comparing with generally used nanotube (CNT), OLC exhibits higher electroactive surface area conductibility. The glassy (OLC/GCE) CNT GCE (CNT/GCE) determined be 0.1508 cm2 0.1231 respectively. Notably, OLC/GCE (Ipc:-139 μA) exhibited reduction peak current contrast CNT/GCE (Ipc:-94 cyclic voltammetry test. Remarkably, under ideal conditions, displayed linear detection range spanning from 0.05 120 μM, an exceptionally low identifying limit 3.74 nM. addition, excellent selectivity, reproducibility, repeatability determining 4-NP. response remains about 92% primal value 15 days later, demonstrating outstanding stability OLC/GCE. Furthermore, successfully employed authentic samples, yielding satisfactory recovery rates ranging 96.14% 102.1%. This investigation exemplifies sensing capabilities promising potential field electrochemically environmental settings, which provides method simple, quantitative

Due to the dearth of extremely capable, sensitive, and stable catalysts, efficient detection catalytic removal 4-nitrophenol (4-NP) in industrial wastewater remains a serious challenge. The determination presence environment is matter paramount importance because it high-priority hazardous pollutant that can affect people, animals, plants. Here, we present promising economically viable green synthetic route for fabricating CuFe2O4 CuFe2O4@Ag hybrid nanocomposites from leaf extract Senna didymobotrya. UV–Vis, FTIR, XRD, FE-SEM, EDXA, BET VSM analysis were performed characterize synthesis nanocomposite. To evaluate electrocatalytic capacity CuFe2O4@Ag, electrochemical sensing stratergy was with cyclic voltammetry (CV) differential pulse (DPV). modified glassy carbon electrode (GCE) (CuFe2O4@Ag/GCE) demonstrated linear response range 0.01-15 μg/ml (71 nm-107 μM) ability detect 4-NP at low concentration (0.006 (43 nM)). increased surface area CuFe2O4@Ag/GCE by ̴ 1.5-fold, greater cathodic current (-16 μA/cm2) potential -0.81 V observed compared CuFe2O4/GCE alone 4-NP. Additonally, showed excellent reduction towards using NaBH4 an efficiency 96.4 % which higher than (only 87.3 %) 12 min due synergistic relationship among Ag NPs nanostructures. outcomes this study shows bi-functional electrocatalyst holds vast environmental remediation.
