Abstract

Highlights: Vanadium nitride-Poly(3, 4-ethylenedioxythiophene)-polyaniline (VN-PEDOT-PANI) hybrid nanocomposites. VN-PEDOT-PANI/GCE as a binder-free modified electrode for the determination of electrocatalytic activity. VN hierarchical porosity with PEDOT-PANI framework produced VN-PEDOT-PANI modified GCE working electrode. The VN-PEDOT-PANI shows strongly enhanced and improved photocatalytic performance of methylene blue (MB). Abstract: In this work, Vanadium nitride-Poly(3, 4-ethylenedioxythiophene)-Polyaniline (VN-PEDOT-PANI) hybrid nanocomposite were synthesized by oxidative polymerization and used for detection of mebendazole (MBZ) drug and photocatalytic degradation of methylene blue (MB) dye. The physicochemical characterization of the VN-PEDOT-PANI composite confirms the two-dimensional (2D) hierarchical porosity of VN and framework of PEDOT-PANI, which provides a binder-free glassy carbon electrode (GCE) supporting the electrochemical catalytic activity. In addition, the formed composite exhibits satisfactory double-layer formation and donor-acceptor behaviour, which supports high-rate capability, good electrochemical cyclic stability, high specific surface area, and electrocatalytic activity towards the detection of mebendazole drug. Furthermore, the versatility of this hybrid composite is confirmed by the improved photocatalytic performance towards the degradation of methylene blue dye and the observation of enhanced efficiency due to the formation of hexagonal morphology of the VN-PEDOT-PANI composite.
