“…With the low resistivity feature of Ti 3 C 2 T x compared to the GCE, the overall conductivity of the modified working electrode ( MXene /GCE) drastically increases, leading to a high electron transfer. This also demonstrates the role of MXene as a conducting platform for charge transport in addition to serving as an active material for electrochemical reduction of 4-NP. − Electrochemical analysis explicitly gives evidence that the chemically exfoliated Ti 3 C 2 T x MXene material is a highly desirable material for electrochemical reduction of 4-NP in the environment.…”

Soil and water contamination by numerous pollutants has been increasingly posing threats to food, water, agriculture, and human health. Using novel nanoscale materials to develop rapid electrochemical sensors is very promising due to the discovery of a number of new two-dimensional (2D) electronic materials. Of particular importance is 2D transition-metal carbide MXene that has been shown to possess transformative properties pertaining to its physical, chemical, and environmental characteristics, leading to their potential sensor applications. Designing electrochemical sensors using MXene has the potential to pave the way for monitoring environmental pollutants. Here, a stacked layer of chemically exfoliated MXene (Ti 3 C 2 T x ) was demonstrated as an electrochemical sensor for detection of 4-nitrophenol (4-NP) with high sensitivity and a low limit of detection. Successful selective exfoliation of the MAX (Ti 3 AlC 2 ) phase of the material by chemical etching without oxidation is shown to be the key to achieving higher sensitivity and a lower detection limit. In the optimal conditions, the proposed MXene sensor electrodes were capable of detecting 4-NP in a broad concentration range from 500 nM to 100 μM with a good linear sensing range (regression fit, R = 0.995). The higher sensitivity and notable limit of detection reached about 16.35 μA μM −1 cm −2 and 42 nM/L, respectively, with good reproducibility and repeatability. The real-time application of the proposed MXene sensor electrodes was confirmed by testing in tap water samples with excellent recoveries of 95−99%.

“…The use of acid solutions is common in industrial processes such as pickling, cleaning, and descaling. Iron, the main constituent of steel is widely used as the main construction material in many engineering fields due to its low cost, high tensile strength, malleability and easy availability [10–12] . The most commonly used surfactant inhibitors are quaternary ammonium‐type cationic surfactants [13,15] .…”

In this study, two cationic gemini surfactants 12-3-12 and 12-3(OH)-12 were synthesized in our labrotory. The critical micelle concentration (CMC) values of synthesized surfactants were determined by conductivity measurements. The aggregation number (Nagg) of micelles was calculated using the pyrene probe fluorescence method. It was been investigated the corrosion effect of cationic gemini surfactants were denoted as 12-3-12 and 12-3(OH)-12 for carbon steel in 1 M HCl. The inhibition effect was investigated using weight loss, electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP) and scanning electron microscopy (SEM) techniques. It has been determined that both surfactants showed the best inhibitory effect at low concentrations. The foaming capacity (FC) and the foam stability (FS) of gemini surfactants were studied by measuring the foam volume for 0.5 % (w/v) surfactant solutions and it was observed that the foaming properties of 12-3(OH)-12 gemini surfactant were better. The solubility capability of both surfactants was tested with the water-insoluble dye Sudan Red B and it was observed that the solubility increased significantly over the CMC value of the cationic gemini surfactants. Finally, the corrosion effect, foam capacity and foam stability and effects on paint solubility of the synthesized surfactants were obtained at very low concentrations.

“…Therefore, applying corrosion inhibitors is considered to be an unavoidable approach, and has been proven to be a convenient, effective and economical technique for protecting metals during such processes [5,11]. It has been revealed that organic compounds containing heteroatoms, unsaturated bonds and planer conjugated systems usually display excellent corrosion inhibition activities because they adsorb onto the metal surface via their functional groups and form a protective film [3,5,18,19]. Unfortunately, traditional inhibitors are often toxic to human beings or have a detrimental impact on the environment, and so their use has been limited by more and more countries.…”

Cucumber (Cucumis sativus L.) Leaf Extract as a Green Corrosion Inhibitor for Carbon Steel in Acidic Solution: Electrochemical, Functional and Molecular Analysis

et al. 2022

An extract of cucumber leaves (ECSL) was prepared as a green corrosion inhibitor for carbon steel. Its carbon steel corrosion inhibition performance against 0.5 mol L−1 H2SO4 was investigated using electrochemical methods and scanning electron microscopy (SEM). Its composition was analyzed by gas chromatography and mass spectroscopy (GC−MS). Quantum chemical calculations and molecular dynamics simulations (MDS) were conducted to elucidate the adsorption mechanism of the inhibitor molecules on the carbon steel surface. The results indicated that the inhibition efficiency increases with its increasing concentration. The extract acted as a mixed type corrosion inhibitor, and its inhibition properties were ascribed to the geometric coverage effect induced by its adsorption on the metal surface in accordance with Langmuir’s law. The active components in the extract were identified as mainly organic compounds with functional groups such as aromatic moieties and heteroatoms. The inhibition activities of ECSL are delivered through the ability of the active components to adsorb on the metal surface through their functional groups to form a protective layer which hinders the contact of aggressive substances with carbon steel and thus suppresses its corrosion. This research provides an important reference for the design of green corrosion inhibitors based on plant waste materials.
