摘要
Abstract A novel molecularly imprinted electrochemical sensor is presented based on one-dimensional ultrathin manganese oxide nanowires/two-dimensional molybdenum titanium carbide MXene (MnO 2 NWs@Mo 2 TiC 2 MXene) for fenitrothion (FEN) determination. After the synthesis of MnO 2 NWs@Mo 2 TiC 2 MXene ionic nanocomposite was successfully completed with a facile hydrothermal and the pillaring methods, a new type molecular imprinted electrochemical sensor based on MnO 2 NWs@Mo 2 TiC 2 MXene was constructed with cyclic voltammetry (CV) polymerization including pyrrole monomer and FEN target molecule. After the characterization studies including spectroscopic, electrochemical and microscopic methods, the analytical applications of the prepared sensor were performed. A linearity of 1.0×10 −9 –2.0×10 −8 mol L −1 was obtained and the values of the quantification limit (LOQ) and the detection limit (LOD) were 1.0×10 −9 mol L −1 and 3.0×10 −10 mol L −1 , respectively. The studies of selectivity, stability and reproducibility of the constructed sensor based on MnO 2 NWs@Mo 2 TiC 2 nanocomposite and molecularly imprinting polymer (MIP) were carried out in detail. Finally, the developed sensor was applied to white flour samples with the values close to 100%. Graphical Abstract
