Abstract
•We fabricated a novel SrMoO4 adorned on the graphitic carbon nitride (SrMoO4/SGCN) nanocomposite via simple sonochemical approach.•As prepared, SrMoO4/SGCN was successfully applied for the electrochemical detection of CAP.•The SrMoO4/SGCN modified electrode exhibits wide linear range and low limit of detection of about 0.005–1316.8 µM and 1.5 nM towards CAP detection, respectively.•The real sample analysis reveals the practical applicability of SrMoO4/SGCN modified electrode for sensing of CAP.
We developed an almond like structured SrMoO4 embedded on sulfur doped-graphitic carbon nitride composites (SrMoO4/SGCN) by green methods for electrochemical detection of CAP. The as-synthesized SrMoO4/SGCN composites was scrutinized by various techniques such as X-ray powder diffraction (XRD), scanning electron microscope (SEM), Transmission electron microscopy (TEM), and elemental quantitative analysis. Interestingly, the impedance of SrMoO4/SGCN/GCE own a lower resistance charge transfer (Rct), which helps to favours for superior electrochemical detection of CAP. Such, SrMoO4/SGCN/GCE exhibits an ultralow detection limit of 1.5 nM for an extensive concentration range of 0.005–1316.8 µM and high sensitivity is 9.619 µA µM−1 cm−2 by amperometric method. In addition, human blood serum and river water samples were used for practical analysis of SrMoO4/SGCN/GCE toward electrochemical detection of CAP and the result exhibits a satisfactory recovery.
