عنوان انگلیسی New Synthesis and Characterization of NiMoO4/Mn(VO3)2 Heterostructures for Electrochemical Detection of Dopamine
چکیده انگلیسی مقاله The goal of this study is to establish a simple and convenient co-precipitation approach for the ultrasonic synthesis of NiMoO4/Mn(VO3)2 heterostructures without capping agents and to adapt the glassy carbon electrode with this material for electrochemical detection of dopamine. To analyze the chemical structure and morphology of nanostructures, field emission scanning electron microscopy (FE-SEM) and X-ray diffraction (XRD) techniques were used. The ultrasonic wave for pure NiMoO4/Mn(VO3)2 heterostructures with homogeneous sphere-like shape and small particle size around 30-40 nm was discovered using FESEM and XRD results. Electrochemical sensors have been sought after for studying biological, environmental, and pharmaceutical species due to their long-term reliability, high sensitivity, and accuracy, as well as their low cost, speed, and ease of shrinking. Differential pulse voltammetry (DPV) and cyclic voltammetry (CV) were used to conduct electrochemical experiments of the GCE/NiMoO4/Mn(VO3)2 towards dopamine (DA) detection. According to the DPV results, the modified sensor revealed a linear concentration range of 1 to 60 μM with a limit of detection of 0.33 M and high selectivity.
