“…It estimates the presence of functional group in the material. The transmittance peak at 3412 and 1650 cm −1 is ascribed due to the presence of –OH stretching vibrations 19,20 . The peak at 2927 cm −1 occurs due to C–H vibrations of organic compounds.…”

“…From the ambient temperature to 150 C (first inflation region) the weight loss is ≈2% which corresponds to the loss of coordinated water from the samples, free water and other organic impurities. 20,23 In second inflation region between 150 C and 450 C, the TG curve exhibits a very small increasing tendency which may be attributed to the absorption of O 2 molecules on the MnTiO 3 surface. After 450 C-900 C (third inflation region), a sudden decrement in weight suggested that the oxidation reaction from Mn 2+ to Mn 3+ starts to occur.…”

In this paper, we report the synthesis of MnTiO3 nanoparticles employing a simple, eco‐friendly and low‐cost hydrothermal method. The properties of MnTiO3 nanoparticles were analysed by XRD, FTIR, FE‐SEM, TEM and thermogravimetric analysis (TGA). Structural properties revealed that the MnTiO3 have rhombohedral phase. Morphological studies revealed that the synthesised sample has granular‐like structure. FTIR technique confirmed the formation of MnTiO3 nanoparticles. TGA shows that the as synthesised sample is thermally more stable. The electrochemical detection of acetaminophen (AMP) by using nano‐perovskite‐type manganese titanate (MnTiO3)‐modified glassy carbon electrode is reported. The conductive behaviour of MnTiO3‐modified glassy carbon electrode (MnTiO3/GCE) was confirmed by cyclic voltammetry (CV). Differential pulse voltammetry (DPV) was employed for the detection of AMP. DPV technique showed a comparatively lower detection potential with a higher peak response towards AMP sensing with a linear range of 1.3 to 13.8 μM. The limit of detection and sensitivity were found 1.26 μM and 36.22 μA μM−1 m−2, respectively. Moreover, the modified electrode also demonstrated better repeatability, reproducibility and higher stability, hence used for the analysis of AMP in pharmaceutical and human serum samples with good recoveries. Electrochemical properties showed that the MnTiO3 perovskite has specific capacitance 357.2 F g−1 revealing its charge storing ability.

“…Despite small pore diameters (1-10 Å), limiting the diffusion of the largest CWAs agents [55,56], some zeolites showed good efficiency for the decontamination of several toxic agents [57][58][59][60][61][62][63][64][65]. A pioneer study was made in 1994 about the interaction of gaseous HD within zeolite 13X [57].…”

“…They showed that AgY was efficient for HD decontamination while NaY was more active towards VX by P-S bond cleavage. Typically, the good results obtained with Agdoped clays and zeolites are attributed to the affinity of silver for the complexation of sulfur-containing compounds [41,55,58,60,61]. In addition to these works, zeolites have also been used as sensors for CWAs (or simulants), evaluating their properties using ionic conductivity measurements or a quartz crystal microbalance [56,62].…”

This paper deals with the preparation of silver/mordenite nanocomposite using aqueous propolis extract along with different concentrations of silver nitrate. The study of the prepared samples' structural properties gave two possibilities for the nanocomposite formation process, and this was confirmed by the UV-visible absorption spectrum and the energy-dispersive X-ray spectroscopy. Unexpectedly, the decrease in the size of these nanocomposites (14-21 nm) showed a non-linear behavior with increasing silver nitrate concentration because of the presence of propolis during urbanization, and this was explained using the results of the transmission electron microscopy images and X-ray diffraction. The Ag/mordenite nanocomposites showed the effective ability to eliminate the two types of bacteria (Gram-positive [Staphylococcus aureus] and Gram-negative [Escherichia Coli]). As well, these nanocomposites demonstrated with simple experiments the removal efficiency of some dyes pollutants (such as methylene blue, methyl orange, malachite green, indigo, and Congo red) from aqueous solutions. These results were explained in this article.
