Abstract In this study, a novel electrochemical method as a conductive voltammetric sensor for determination of N-hydroxysuccinimide was developed. The N-hydroxysuccinimide sensor was achieved by carbon paste electrode (CPE) amplified with tri-component nanohybrid composite (Platinum nanoparticle/Polyoxometalate/Two-dimensional hexagonal boron nitride nanosheets) (PtNPs/POM/2D-hBN) and 1-hexyl-3-methylimidazolium chloride (HMICl) as conductive mediators. A significant decrease (110 mV) in the oxidation overvoltage and significant increased (2.4 times) in the current of the N-hydroxysuccinimide were observed using HMICl-PtNPs/POM/2D-hBN/POMBNS/CPE. Furthermore, the HMICl-PtNPs/POM/2D-hBN/POMBNS/CPE exhibited a good linearity from 0.1 to 300 μM and detection limit 60 nM for determination of N-hydroxysuccinimide. The capability to promote the electron exchange between N-hydroxysuccinimide and the HMICl-PtNPs/POM/2D-hBN/POMBNS/CPE exhibited a novel analytical strategy for fabrication of water pollutant sensor.
