Construction of Sr@Mn₃O₄/GO nanocomposite: a synergistic electrocatalyst for nitrofurantoin detection in biological and environmental samples

Abstract

Currently, antibiotic drugs based on nitro-group derivatives are crucial for the treatment of urinary infections in human beings. Nonetheless, the overuse of antibiotics may cause harmful effects on the ecosystem...

High‐Performance 2.2 V Asymmetric Supercapacitors Achieved by Appropriate Charge Matching between Ultrahigh Mass‐Loading Mn3O4 and Sodium‐Jarosite Derived FeOOH

“…In addition, the Raman spectrum of the Mn 3 O 4 @ACC declares that the presence of three peaks at 315 cm −1 , 365 cm −1 , and 654 cm −1 is attributed to the Mn─O bond of Mn 3 O 4 in Figure 1c. [ 28 ] D peak at 1340 cm −1 and G peak at 1590 cm −1 are attributed to disordered sp 3 carbon and crystalline graphite sp 2 carbon separately. [ 29 ] Typically, the Fourier transform infrared spectroscopy (FTIR) spectra in Figure S2a (Supporting Information) are used to analyze the functional groups contained on the ACC and Mn 3 O 4 @ACC surface.…”

An ultra-sensitive electrochemical sensor based on MOF-derived ZnO/Co3O4decorated on graphene for low-level monitoring of the α1-AR antagonist alfuzosin in tablets and human samples

“…1f ) contains three Gaussian peaks at the binding energies of 284.77, 286.34, and 288.71 eV, attributed to sp 2 hybridized C-C/CvC, C-O-C, and CvO groups in the composite. 52 Table 1 summarizes the XPS data of the ZnO/Co 3 O 4 @Gr nanocomposite.…”
