In this study, neodymium nickelate nanoparticles were successfully synthesized using a simple coprecipitation method. The modified NNO-500/SPCE sensor exhibited excellent electrocatalytic activity and low electron transfer resistance for the detection of prochlorperazine. The sensor showed a low limit of detection, wide linearity range, and high selectivity, stability, and precision.
In this study, the synthesis of neodymium nickelate (Nd2NiO4, NNO) nanoparticles with diverse temperatures were developed by the simple coprecipitation method. The successfully prepared NNO was characterized with various spectroscopic instruments. The surface morphology, size, shape, composition, crystallinity, functionality, bonding, and the presence of elements of the nanoparticles were analyzed by suitable characterization techniques. The electrochemical features were investigated by electrochemical impedance spectroscopy, cyclic voltammetry, and differential pulse voltammetry (EIS, CV, and DPV) methods. As results expected, the modified NNO-500/SPCE sensor displays low electron transfer resistance (Rct), high active surface area, and excellent electrocatalytic activity for the detection of prochlorperazine (PCP) rather than other electrodes. Under optimized electrochemical detections, the DPV study revealed a low limit of detection (LoD), and limit of quantification (LoQ) of 4 nM, and 14 nM with wide linearity of 0.025-1220 mM for PCP at the NNO-500 sensor. In addition, high selectivity, stability, precision, and satisfactory recoveries in biological samples for PCP detection. Thus, our study provides a simplistic but effective method for constructing perovskite-type materials with excellent electrochemical performance.
