Abstract
Iron oxide ornamented carbon nanotube nanocomposites (Fe3O4.CNT NCs) were prepared by a wet-chemical process in basic means. The optical, morphological, and structural characterizations of Fe3O4.CNT NCs were performed using FTIR, UV/Vis., FESEM, TEM; XEDS, XPS, and XRD respectively. Flat GCE had been fabricated with a thin-layer of NCs using a coating binding agent. It was performed for the chemical sensor development by a dependable I-V technique. Among all interfering analytes, 3-methoxyphenol (3-MP) was selective towards the fabricated sensor. Increased electrochemical performances for example elevated sensitivity, linear dynamic range (LDR) and continuing steadiness towards selective 3-MP had been observed with chemical sensor. The calibration graph found linear (R2 = 0.9340) in a wide range of 3-MP concentration (90.0 pM ~ 90.0 mM). The limit of detection and sensitivity were considered as 1.0 pM and 9×10−4 μAμM-1cm-2 respectively. The prepared of Fe3O4.CNT NCs by a wet-chemical progression is an interesting route for the development of hazardous phenolic sensor based on nanocomposite materials. It is also recommended that 3-MP sensor is exhibited a promising performances based on Fe3O4.CNT NCs by a facile I-V method for the significant applications of toxic chemicals for the safety of environmental and health-care fields.
Highlights
The protection is a key apprehension in viewpoint of atmosphere and health that is a great issue to examine using sensors intended for the identification & recognition of toxic materials through an established practice
The UV/Vis. spectra of the Fe3O4 NPs and Fe3O4.carbon nanotube (CNT) NCs were recorded in the visible range (200 ~ 800 nm)
The band-gap energies for Fe3O4 NPs and Fe3O4.CNT NCs were found as 2.5 and 2.3 eV correspondingly (Fig 1B–1D) [51,52,53]
Summary
The protection is a key apprehension in viewpoint of atmosphere and health that is a great issue to examine using sensors intended for the identification & recognition of toxic materials through an established practice. Different methods reported for the isolation and removing of carcinogenic materials from the industrial waste water but a few issues are still remaining troubled that are removing of toxic agents in efficiently and re-usability of the NCs materials including their preparation at a facile and low cost. Substituted and un-substituted phenols are common bi-products of industrial process having high toxicity properties. They are frequent contaminants in food, fresh and waste water [24]. Based on different nanostructure materials, semiconductor undoped or doped nanomaterials (NMs), transition metal oxides, electrocatalytic moieties, several chemically modified electrodes have been developed for the detection of 3-MP [25]
