Zinc Manganate: Synthesis, Characterization, and Electrochemical Application toward Flufenamic Acid Detection.

摘要: The construction of novel electrocatalysts for efficient and economic electrochemical sensors is continuously a significant conceptual barrier the point-of-care technology. Binary metal oxides with heterostructures have gained plenty attention due to their promising physicochemical properties. Herein, we develop rapid sensitive probe detection flufenamic acid (FFA) by using zinc manganate (ZnMnO)-modified electrode. formation ZnMnO was confirmed various analytical techniques, such as X-ray diffraction, Raman spectroscopy, Fourier transform infrared transmission electron microscopy, field-emission scanning microscopy energy dispersive spectroscopy elemental mapping. ZnMnO-based electrocatalyst, which used FFA, shows better performance than previously reported electrode materials. assay linear quantitative range from 0.05 116 μM limit 0.003 sensitivity 0.385 μA μM-1 cm-2. Its good can be ascribed large surface area, charge mass transfer, copious active sites, high carrier mobility. study displays that fabricated sensor has potential applied in clinical analysis. This work constructs an advanced functional material microscale architecture
