“…In the next step, for more clarity and identifying functional groups and molecular structure, FT‐IR analysis was used. In Figure B, the major characteristic bands belong to GO, are at 1750, 1322, 1112 cm −1 that attributed to C=O, C−O−C and C−O stretching vibrations . For 35MIL (Fe)‐53@GO, the located bands at 1625 cm −1 , 1537 cm −1 and 1430 cm −1 are corresponded to asymmetric stretching of COOH .…”

A novel, stable and sensitive non‐enzymatic sensor was developed with metal‐organic frameworks (MOFs) that have attracted great attention in electrochemical sensors applications in recent years. The pore structures of MIL (Fe)‐101 and MIL (Fe)‐53 are the families of MOFs that were constructed via a simple solvothermal procedure. The 35MIL‐101(Fe)‐reduced graphene oxide nanocomposite has been used for modification of glassy carbon electrode for the determination of carbofuran (CBF) and carbaryl (CBR). The porosity of the composites increased the voltammetric responses significantly for CBF and CBR in a mixed solution that makes the simultaneous determination of both carbamate pesticides possible. Characterization of MIL (Fe)‐101 and MIL (Fe)‐53 were performed with FT‐IR, XRD, BET and SEM. Finally, the introduced sensor under the optimal conditions showed low detection limits of 1.2 and 0.5 nM within the linear ranges of 5.0–200.0 nM and 1.0–300.0 nM for CBF and CBR, respectively. The non‐enzymatic sensor was successfully used to monitoring of carbamates residue in vegetable and fruit samples.

“…The peak at 1403 cm -1 was attributed may be also due to adsorption of carbonate group [21]. The peak at 1200 cm -1 is attributed to C-OH stretching vibrations [22]. The peak at 1380 cm -1 is assigned to symmetric stretching of CO 3 2- [23].…”

Polymer based nickel (Ni) and cobalt (Co) co-doped ferrites were prepared by adept ultrasonication route. Different concentrations of polymer [polyvinyl alcohol (PVA)] (0.2 g and 0.5 g) was added as a surfactant to the magnetic particles. The phase purity of Ni-Co ferrites (spinel structure) was confirmed by X-ray diffraction (XRD). Enhanced saturation magnetization of polymer based magnetic nanoparticles due to shape anisotropy and size. 0.2 wt% doped ferrite showed superparamagnetic characteristics with blocking temperature above room temperature. Hence, ultrasonication route is a rapid and effective technique for tailoring size and morphology of magnetic nanostructure that could be useful in magneticsensor applications.

“…Recently, transition metal oxides, which include Fe 2 O 3 ÀMn 2 O 3 , NiO, and V 2 O 5 , have been explored as the sensing materials for hydrazine detection. [84][85][86] The addition of Fe in Mn 2 O 3 catalyst has been found essential to maintain 3D net-like framework and provided large electroactive surface area, therefore, more exposed active sites for the electrochemical response. [78] Cobalt-based oxides including CoOOH, CuCo 2 O 4 , Co 3 O 4 with different nanostructures have been extensively utilized as a modifier to detect hydrazine with satisfactory results.…”
