fabrication of a sensitive electrochemical sensor using a wet-chemically prepared ternary ZnO/MgO/CrO nanofiber (NF)-decorated glassy carbon electrode (GCE) with Nafion adhesive was the approach of this study. The resultant NFs were characterized by various tools, such as powder X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), Brunauer-Emmett-Teller (BET) surface area analysis, and ultraviolet-visible spectroscopy (UV/Vis). The analytical parameters of the proposed toluene sensor were characterized as follows: good sensitivity (23.

In this work, a tri-metal based nanocomposite was synthesized and characterized. A detailed investigation of the photocatalytic dye degradation efficiency of the nanocomposite under visible light showed promising results in a wide pH range, both acidic and basic medium. Studies on anti-bacterial activity against seven pathogenic bacteria, including both Gram positive and Gram negative species, were conducted in the presence and absence of light and compared with the standard antibiotic gentamicin.

An easy and reliable wet-chemical method was used to synthesize iron oxide doped zinc oxide nanoparticles (FeO@ZnO NPs) at a low-temperature under alkaline medium. The electrochemical characteristics of FeO@ZnO NPs were investigated by using different electrochemical techniques such as UV-vis, FTIR, XRD, FESEM, XEDS, and XPS. A sensor was fabricated by deposition of a thin covering of FeO@ZnO NPs onto a flat dried glassy carbon electrode (GCE) with a polymer matrix with conducting characteristics (Nafion, Nf).

A simple wet-chemical technique was used to prepare zinc oxide-doped vanadium pentaoxide nanorods (ZnO·VO NRs) in an alkaline environment. The synthesized ZnO·VO NRs were characterized using typical methods, including UV-visible spectroscopy (UV-Vis), Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectroscopy (XEDS), X-ray photoelectron spectroscopy (XPS), and X-ray powder diffraction (XRD). The d-glucose (d-GLC) sensor was fabricated with modification of a slight coating of nanorods (NRs) onto a flat glassy carbon electrode (GCE).

The facile hydrothermal method was used to prepare low-dimensional doped AgO/SbO nanoparticles (NPs) at low temperature in alkaline medium. The calcined NPs were characterized in detail by FTIR, UV/vis, FESEM, XPS, EDS, and XRD. A thin layer of AgO/SbO NPs was deposited onto a glassy carbon electrode (GCE) using Nafion (5% Nafion suspension in ethanol) conducting binder, which formed the working electrode of the selective 3-methoxyphenol electrochemical sensor probe.
