Facile synthesis of perovskite materials for the electrochemical sensing applications are remains challenging. In the current work, a simplified electrochemical sensor system based on an electrode modifier containing LaNiO3 was developed to detect catechol (CC). The surface micrograph of LaNiO3 was examined using X-ray diffraction pattern (XRD), X-ray photoelectron spectroscopy (XPS), and High-resolution transmission electron microscopy (HRTEM). Besides, the LaNiO3 reveals a remarkable electrooxidation response for the detection of catechol by cyclic voltammetry (CV) and amperometry techniques. The suggested sensor platform shows a broad linear range for catechol detection from 5 µM to 2000 µM with LOD and sensitivity of 0.6 µM and 54 µA cm−2 mM−1, respectively, under optimised conditions. Furthermore, LaNiO3 altered GCE was fruitfully implemented for the quantification of catechol in tap water sample. [ABSTRACT FROM AUTHOR] |
