Facile green synthesis of graphene–titanium nitride hybrid nanostructure for the simultaneous determination of acetaminophen and 4-aminophenol

摘要: Abstract We demonstrate herein a newly developed electrochemical sensor base on the reduced graphene oxide–titanium nitride (RGO–TiN) nanohybrid. The nanohybrid was prepared by mixing TiN nanoparticles and GO dispersion then treating with glucose Zn foils. morphologies microstructures of as-prepared were characterized UV–vis absorption spectroscopy, X-ray photoelectron transmission electron microscopy Raman spectroscopy. RGO–TiN exhibited excellent electrocatalytic activity toward simultaneous detection acetaminophen (ACOP) 4-aminophenol (4-AP). As result, linear ranges 0.06–660 μM for ACOP 0.05–520 μM 4-AP, respectively, low limits 0.02 μM 0.013 μM 4-AP. Based performance, it demonstrated that promising candidate advanced electrode material in sensing field may find more applications various analytes.
