“…Moreover, the graph between the peak current and square root of scan rate shows a linear relationship, which exhibits that pristine and Fe doped MnSnO 3 nanomaterials are diffusion-controlled reactions in nature. 31,32 Figure 10 shows the Nyquist plot of pristine and Fe doped MnSnO 3 . None of the samples showed a circular arc in the high-frequency region but all the samples show almost a straight line in the low-frequency region called Warburg resistance, which is caused due to the frequency dependence of ion diffusion from the electrolyte to the surface.…”

The present article investigates the fabrication of MnSnO 3, and Fe doped MnSnO 3 perovskite. We are reporting for the first time Fe doping perovskite material. The synthesis has been carried out under subcritical conditions. The optical, electrochemical, and luminescence properties were investigated. The structural determination of nanostructures has been carried out through XRD and Fourier transform infrared (FTIR). Furthermore, scanning electron micro-

“…The crystallite size of the optimised sample can be estimated by the Scherrer equation

D = \frac{italicKλ}{β Cos θ},

where D is the crystallite size of the synthesised material, λ = 0.15418 nm, K = 0.9 is the shape factor, β is the full‐width half maxima and θ is the diffraction angle 17,18 . The crystallite size of the synthesised materials ranging from 2.85 to 6.64 nm with 0.0023 lattice strain.…”

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.

“…It is recommended as a promising adsorbent for its unique porous structure, surface area and environmentally green chemical product. 14,25 It is built up with an AlO 4 and SiO 4 tetrahedral framework, forming a 3D structure. In addition, the spectroscopic evidence from many studies proves that the polymer matrix is formed within the ZT channel system or on the surface and it exists in the conductive form of PANI which includes localized/delocalized polaronic and bipolaronic structures in diverse proportions.…”

Copper oxide−zeolite (CuO−ZT) reinforced polyaniline (PANI) matrices were prepared by in situ oxidative polymerization and the samples were characterized by X‐ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, XRD, TGA, UV–visible spectrophotometry, SEM and Brunauer–Emmett–Teller theory; the optical bandgap was also evaluated. Moreover, the synthesis and exploration of electrodes are increasingly being considered for the development of conducting‐polymer‐based supercapacitors, which has attracted significant interest in energy conversion and storage technology. Here, hybrid materials used in the preparation of the electrode materials on the capacitive properties were investigated. It is found that the PANI@CuO exhibits a high specific capacitance of 311.5 F g−1 at 1.0 A g−1 current density between 0.0 and 1.0 V compared to PANI@CuO−ZT (222.7 F g−1). Further, the PANI@CuO presented an excellent cycling stability at 1.0 A g−1 (1500 cycles; 81.9%) in a two‐electrode system. Accordingly, producing a PANI matrix on CuO presented a simple and viable way to ameliorate the capacitive performance of the supercapacitor. Conversely, the adsorptive removal of malachite green and methyl violet dyes by PANI@CuO−ZT adsorbent could be described by the pseudo‐first‐order and Temkin models. The maximum adsorptive capacity of malachite green and methyl violet dyes was 249.7 and 198.2 mg g−1, respectively. © 2023 Society of Industrial Chemistry.
