Here the performance in 4-Nitrophenol (4-NP) detection of magnetite-few layer graphene-based electrode was reported. The prepared nanocomposite, synthesized according to a "wet chemistry" approach, was broadly characterized: SEM and TEM images and XRD spectra indicate the formation of nanoparticles with a few nanometers size dispersed on graphene layers. The sample was tested as an electrochemical sensor for the detection of small traces of 4-NP in aqueous solutions with a limit of detection (LOD) of 4 μM. The sensor was tested also for 1 month, showing proper operation and excellent stability.

Abstract
Here the performance in 4-Nitrophenol (4-NP) detection of magnetite-few layer graphene-based electrode was reported. The prepared nanocomposite, synthesized according to a "wet chemistry" approach, was broadly characterized: SEM and TEM images and XRD spectra indicate the formation of nanoparticles with a few nanometers size dispersed on graphene layers. The sample was tested as an electrochemical sensor for the detection of small traces of 4-NP in aqueous solutions with a limit of detection (LOD) of 4 μM. The sensor was tested also for 1 month, showing proper operation and excellent stability.File in questo prodotto:
