Defect-rich hexagonal boron nitride for the simultaneous determination of 4-aminophenol and phenol

A new electrochemical sensor has been developed for the simultaneous determination of 4-aminophenol (4-AP) and phenol (Ph) based on the defect-rich hexagonal boron nitride (D-h-BN). The D-h-BN was prepared via one-step calcination route using a single-source precursor. The obtained D-h-BN was structurally characterized by X-ray diffraction (XRD), fourier transform infrared (FTIR) spectroscopy and transmission electron microscopy (TEM)....
