Résumé: Abstract The need for more accurate, smaller, and more capable sensors was felt as a result of global scientific advancements, the creation of electronic equipment, and the significant changes that occurred over the last several decades. These days, sensors with high affectability are used, making them sensitive to even little amounts of radiation, heat, or gas. The discovery of underutilized materials and equipment is necessary to increase the affectability, proficiency, and accuracy of these sensors. Because of their small and nanoscale readings, nano sensors which are nanometer-sized sensors have remarkably high accuracy and responsiveness, allowing them to react when a gas is just a few iotas away. Compared to conventional sensors, Nano sensors are inherently smaller and more sensitive.
Résumé: Abstract This study aimed to develop a cost-effective and eco-friendly catalyst for removing persistent dyes from water. This was achieved by utilizing the photocatalytic properties of Fe[Fe(CN)5NO], which was immobilized on a phyllosilicate clay (FeNP@Kao). This catalyst was successfully obtained by the in situ reaction between Fe(II) ions and nitroprusside anions [Fe(CN)5NO] on the surface of kaolin. The obtained material was subsequently characterized by FTIR spectrometry, X-ray diffraction, scanning electron microscopy, UV–vis spectroscopy, and BET Analysis. The experimental analysis shows that the Fe[Fe(CN)5NO] the complex is well infiltrated on the surface of the used clay. The sono-photodegradation trials were optimized under the effect of four operating factors, including FeNP@Kao amount (0.25–1.50) gL−1, solution pH(1–6), H2O2 quantity (0–0.075) mol L1 , and methyl violet 10B initial concentration (5–50) mgL−1. The attained results illustrate that methyl violet 10B elimination increased with the rise of the H2O2 concentration and the catalyst dose. The optimum conditions determined at room temperature were CMV10B═15 mgL−1, mFeNP@K═1 gL−1, mathematical equation= 0.060 mol L−1, and pH = 3 with a total removal efficiency (100%) achieved after 60 min of reaction. The results showed that the FeNP@Kao is an outstanding visible-light-driven catalyst material for the photodegradation of MV10B under visible-light irradiation
