摘要: The present work describes the electrochemical 4-chlorophenol (4-CP) sensing properties of multilayer graphene samples (MLG). In order to enhance presence oxygen functional groups and increase edge plane defects, plasma treatment is adopted. Raman, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) atomic force (AFM) characterizations are used investigate effect on MLG. Compared pristine MLG, treated one shows increased oxidation current towards 4-CP. sensor data exhibit high sensitivity stability with anti-interference property in other phenolic compounds including phenol, bisphenol, 2,3-chlorophenol, 2,3,4-nitrophenol inorganic ions.
