“…The current intensity was increased in the enhancement of the p-nitrophenol amount in the aqueous media. The identical trend is also reported for different toxin monitoring 16,50–52 . In a suitable protocol, the p-nitrophenol was involved to fewer amounts of surface sites of the binary SnO 2 /CdO MCs and oxidation process of the p-nitrophenol starts gradually.…”

Development of highly efficient and potential material for toxic p-nitrophenol is an important design for sensitive detection of hazardous species from ecology and environment. Here it is developed, an efficient as well as selective of p-nitrophenol using binary material by electrochemical performances, including good linearity, lower detection limit, good stability, higher reproducibility and extreme sensitivity. The prepared electrode was fabricated by immobilization of SnO2/CdO microcubes (MCs) with conducting coating binders by using well-known glassy carbon electrode (GCE). The proposed MCs with SnO2/CdO were well-functionalized and prepared by facile hydrothermal technique. The general instrumentation namely, FTIR, UV/vis, FESEM, XPS, TEM, EDS, and powder XRD were employed for the morphological evaluation of the prepared doped MCs, structural, optical and elemental analyses. The large dynamic range (LDR) from 1.0 to 0.01 mM with 0.13 pM detection limit (S/N = 3), limit of quantification (LOQ; 0.43 pM), and an excellent sensitivity of 7.12 µAµM−1cm−2 were exhibited by the fabricated binary material based on SnO2/CdO MCs for selective p-nitrophenol capturing. In shortly, the SnO2/CdO MCs can be employed as an efficient electron mediator with binary materials fabricated GCE for capturing the p-nitrophenol at ultra-trace amounts. Then the binary synthesized material of SnO2/CdO MCs is used as potential and sensitive sensor layer by stable electrochemical approach for sensitive capturing of toxic p-nitrophenol from environmental samples.

“…The resultant current value is observed maximum for p-nitrophenol compared to other compounds in identical condition by electrochemical method. This is also noted that the binary SnO 2 /CdO MCs has a quick response time with extreme sensitivity, then the present materials can exhibit extreme removal and excellent biocompatibility 22,50,52 .…”

“…b, the I‐V responses are varied with corresponding concentration of Y 3+ ion. The similar tendency of electrochemical response was reported to detect various heavy metal ions . At very early stage of detecting performance of Y 3+ ion, the smaller surface coverage on the surface of C‐PMMA/CNTs e /binder/GCE due to absorption of few molecules of Y 3+ ion and with time being, the corresponding surface coverage and reactions are increased to its steady state equilibrium saturation condition.…”

This article explains how composite thin films, that are made of both cross‐linked poly(methyl methacrylate) (PMMA) and reinforced with multi‐walled carbon nanotube (CNTs), are designed, fabricated and developed for selective cationic sensing applications. The C‐PMMA‐CNTsa‐e nanocomposites were prepared by in situ cross‐linking reaction technique using 4,4′‐diaminobiphenyl (DABP) as the cross‐linking agent. Variable loading of CNTs varied from 2 to 40 wt% was utilized during the cross‐linking process. The nanocomposite films have been structurally characterized by Fourier transform infrared and XRD and the results confirm the incorporation of CNTs in the C‐PMMA matrix, while the dispersion of CNTs in C‐PMMA was characterized using SEM and TEM. The dispersion of CNTs in the composites was excellent, even at high CNTs loading as indicated by SEM and TEM. TEM images of C‐PMMA‐CNTs nanocomposites reveal a core‐shell structure in which CNTs as the core and C‐PMMA as the shell. The thermal features of the nanocomposite films were investigated through their TGA and DTG data. The results confirmed the importance of CNTs content in enhancing the thermal stability of the nanocomposite. The desired yttrium (Y3+) cation sensor was fabricated using glassy carbon electrode coating with a thin uniform layer of synthesized C‐PMMA‐CNTse nanocomposite. A calibration curve was plotted as current vs. concentration of Y3+ ion. The resulted calibration curve is found linear over linear dynamic range of 0.1 nM–0.1 mM. The slope of calibration curve is used to measure the sensitivity (27.2943 μA μM−1 cm−2), limit of detection (3.48 ± 0.17 pM), and limit of quantification (LOQ; 11.6 ± 0.57 pM) of Y3+ cation. It is also found as reliable sensor to detect Y3+ ion in real environmental samples. Considering the contamination of environment, this research might be reliable way for the development of future prospective cationic sensor for the safety of healthcare and ecological fields. POLYM.
