“…A comparison with CZO indicates the embedding of CZO within the rGO matrix. The Debye−Scherrer formula (D = kλ/β cos θ) 34 was employed to compute the crystallite size of CZO and the CZO/rGO nanocomposite, yielding average sizes of 3.67 and 4.28 nm, respectively. Additionally, the surface area of the material was investigated through Brunauer−Emmett−Teller (BET) analysis (Figure S1A).…”

The necessity for highly sensitive and precise methodologies for monitoring water quality and safety is imperative. The substantial health risks linked with Nhydroxysuccinimide (NHS) in water samples and its contact with the skin and eyes are noteworthy. Despite the utilization of numerous techniques for NHS analysis, the adoption of a rapid and uncomplicated electrochemical process has been infrequent. This article details the fabrication of an electrochemical NHS detection system using a cerium zirconium oxide (CZO)-doped reduced graphene oxide (rGO) nanocomposite. The CZO/ rGO nanocomposite was prepared through a straightforward method involving precipitation and sonication. Structural analysis of the CZO/rGO involved various techniques, including X-ray diffraction (XRD), high-resolution transmission electron microscopy (HR-TEM), Raman spectroscopy, field emission scanning electron microscopy (FE-SEM), elemental mapping, energy dispersive X-ray analysis (EDX), and X-ray photoelectron spectroscopy analysis (XPS). Crucial kinetic parameters, such as the effective surface area, were evaluated for CZO/rGO on the glassy carbon electrode (GCE). Additionally, the CZO/rGO/GCE showcased reduced charge transfer resistance (R ct = 99 Ω), exceptional electrochemical activity, a high electron transfer rate, and strong selectivity. This electrode demonstrated excellent electrochemical sensing capabilities for NHS, boasting an extremely low detection limit (0.045 μM) and heightened sensitivity of 0.020 μA μM −1 cm −2 . Demonstrating its potential for swiftly detecting NHS in river water, the CZO/rGO/GCE sensor achieved over 97% recovery. This approach is particularly well-suited for creating water pollution sensors in various sensing devices.

“…2b. 31,32 Weak bands at 689 cm −1 and 531 cm −1 are also produced by the symmetric and asymmetric stretching of the O-W-O bridge in the 750-500 cm −1 frequency range. The bridging and terminal W-O bond in-plane rotation, as well as the deformation into the plane wrenching and terminal rotation, can also be attributed to the bands at 335 cm −1 and 405 cm −1 .…”
