“…The absorption bands at wave numbers 831.26cm -1 , 831.10cm -1 , 829.18cm -1 , 829.19cm -1 , and 829.95cm -1 represent the state of the C=C group. Functional Group C=C is a functional group owned by Polypyrrole, in another research [7], which stated that there was a similarity in the absorption of polypyrrole functional groups in PPy/bacterial cellulose composites indicating the synthesis of PPy/bacterial cellulose was successful. This can be seen by the stretching vibration for the C=C bond which is a characteristic of polypyrrole.…”

The composite is a material that is very important in inserting nanoparticles that act as fillers in a matrix. The filler used in this study is Fe3O4 and the matrix used as a polymer is Polypyrrole (PPy). This research aims to analyze the microstructure of Fe3O4 /PPy composite synthesized by sol-gel method. This research was conducted by varying the composition of Fe3O4:PPy including 30%, 40%, 50%, 60%, and 70% w/w. The sample was characterized by Fourier Transform Infrared (FTIR) and Scanning Electron Microscope (SEM). The results of the FTIR characterization, it was found that the Fe3O4 /Polypyrrole has functional groups O-H, C≡C and C=C. The results of SEM characterization, the particle sizes of each variation composition of Fe3O4:PPy 30%, 40%, 50%, and 70% w/w are 3µm, 3.1µm, 4µm, and 4.5µm, respectively. Based on the results of the study, the greater the composition of the polypyrrole, the greater the particle size.

“…The curve (a) of the Fe 3 O 4 @PPy microcomposite seemingly reveals peaks of both the PPy and Fe 3 O 4 components shown in curves (b) and (c), respectively. The peak observed at 541 cm −1 in Fe 3 O 4 and Fe 3 O 4 @PPy spectra corresponded to the absorption peak of the Fe-O group [34]. The peaks at 924 cm −1 and 1205 cm −1 are observed at almost the same place in both PPy and Fe 3 O 4 @PPy curves and are attributed to C-C out-of-plane ring deformation and C-N stretching vibrations, respectively [35].…”

“…Furthermore, the peak observed at 1044 cm −1 in PPy and Fe 3 O 4 @ PPy spectra shows the C-O-C absorption function of a shift in the stretching vibrations when PPy was added, which is due to energy changes and the PPy-Fe 3 O 4 interaction [34, S36]. Besides that, the appearance of a peak at 3393 cm −1 is attributed to the existence of -OH groups on the surface of the Fe 3 O 4 [S37], which is a vibration of stretching and bending [34].…”

Use of polypyrrole ferrite microparticles and liquid chromatography-mass spectrometry for testing natural grass contamination by multiclass mycotoxins

An analytical methodology based on the combination of dispersive magnetic solid-phase extraction (DMSPE) and liquid chromatography-mass spectrometry (LC-MS) is proposed to explore the occurrence of 13 mycotoxins (aflatoxins B1, G1, B2, and G2; deoxynivalenol; T-2 toxin; ochratoxin A; HT-2 toxin; enniatins A, A1, B, and B2; and beauvericin) and their derivatives in natural grass samples. Magnetic microparticles (Fe3O4) coated with polypyrrole (PPy) polymer were used in DMSPE sample treatment as adsorbent phase, and Fourier-transform infrared spectroscopy, field emission scanning electron microscopy, and energy dispersive X-ray spectroscopy have been used for its characterization. The experimental parameters influencing the adsorption and desorption steps of DMSPE have been optimized. Method validation has been carried out obtaining limits of quantification between 0.07 and 92 μg kg−1 corresponding to enniatin B or A1 and DON, respectively. A total of 83 natural grass samples from 8 dehesa farms were analysed. Enniatin B was found in all the samples (0.29 to 488 μg kg−1 concentration range) followed by enniatin B1 (92.8% of the samples) with a 0.12–137 μg kg−1 concentration range. Moreover, co-occurrence of mycotoxins was studied and between 2 and 5 mycotoxins appeared simultaneously in 97.6% of the samples. Distribution of the contamination according to natural grass location was also investigated. Graphical abstract

“…Judicious choice of support plays a crucial role in affecting the metal–support interaction, which leads to substantial changes in the activity and selectivity of the catalyst. In this context, iron oxide nanoparticles have emerged as outstanding and promising solid support materials due to their abundant availability, easy preparation techniques, lack of toxicity, chemical stability, and ease of separation by an external magnet . In addition, there is a massive prospect for enhancing the active catalytic sites when transformed from bulk to the nanosized regime (<10 nm) .…”

Catalysts with active, selective, and reusable features are desirable for sustainable development. The present investigation involved the synthesis and characterization of bearsurfaced ultrasmall Pd particles (<1 nm) loaded onto the surface of magnetic nanoparticles (8−10 nm). The amount of Pd loading onto the surface of magnetite is recorded as 2.8 wt %. The characterization process covered the utilization of scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), transmission electron microscopy (TEM), inductively coupled plasma (ICP), and X-ray photoelectron spectroscopy (XPS) methods. The Pd@Fe 3 O 4 catalyst has shown remarkable efficacy in the hydrogenation of quinoline, resulting in the production of >99% N-ring hydrogenated (py-THQ) product. Additionally, the catalyst facilitated the conversion of nitroarenes into their corresponding aniline derivatives, where hydrogen was achieved by H 2 O molecules with the aid of tetrahydroxydiboron (THDB) as an equilibrium supportive at 80 °C in 1 h. The high efficiency of a transfer hydrogenation catalyst is closely related to the metal−support synergistic effect. The broader scope of functional group tolerance is evaluated. The potential mechanism underlying the hydrogenation process has been elucidated through the utilization of isotopic labeling investigations. The application of the heterocyclic compound hydrogenation reaction is extended to formulate the medicinally important tubular polymerization inhibitor drug synthesis. The investigation of the recyclability of Pd@Fe 3 O 4 has been conducted.
