Abstract

In this work, lanthanum molybdate nanospheres (LMNSs) were prepared by employing a co-precipitation methodology, and their electrochemical activity against nitrofurantoin (NF) was reported. The physico-chemical nature of LMNSs, and their texture and morphology were characterized by using X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, powder X-ray diffraction (PXRD) and field emission scanning electron microscopy (FE-SEM) combined with energy-dispersive X-ray spectroscopy (EDX). The electrochemical studies were performed by using cyclic voltammetry (CV) and differential pulse voltammetry (DPV) techniques. The ensuing LMNSs have a fantastic active surplus area and uplifted surface volume ratio, which drives the selective and sensitive detection of NF. The as-synthesized LMNSs were coated on a screen-printed carbon electrode (SPCE) by a drop cast method, and the constructed LMNSs/SPCE acts as a potential sensing material towards the reduction of NF. Also, the designed sensor exhibits a broad linear range from 0.01 to 144 μM with a lower detection limit of 72 nM and sensitivity equivalent to 2.94 μA μM−1 cm−2 for the detection of NF. Meanwhile, the fashioned sensor has good selectivity in the presence of metal ions, biomolecules and similar nitro group containing drugs.
