An alternative electrochemical approach for toluene detection with ZnO/MgO/CrO nanofibers on a glassy carbon electrode for environmental monitoring.

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.

The fabrication of a chemical sensor with PANI-TiO nanocomposites.

In this study, conjugated conducting polyaniline was fabricated onto titania nanoparticles (PANI-TiO NPs) using a microwave-accelerated reaction system. The synthesized nanoparticles were characterized using the techniques of electron microscopy (, FE-SEM and TEM), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), and ultraviolet-visible (UV-Vis) spectrometry. An ultrasensitive sensor using the electrochemical (-) approach was fabricated using a thin film of PANI-TiO NPs on a glassy carbon electrode (GCE), and it was found to be selective towards 1,2-diaminobenzene (1,2-DAB) in a buffer phase.

Detection of toxic choline based on MnO/NiO nanomaterials by an electrochemical method.

In this study, a novel choline sensor was assembled by attaching the binary MnO/NiO nanoparticles (NPs) onto a glassy carbon electrode (GCE). Initially, MnO/NiO NPs were synthesized a wet-chemical process and fully characterized XRD, XPS, FESEM, EDS, FTIR and UV-Vis methods. The analytical performances of the choline sensor were evaluated by an electrochemical method in the phosphate buffer phase.
