“…“An adsorbent typically sticks to a surface by forming bonds or through chemical or physical adsorption [ 62 ]. When the conditions are acidic, heteroatoms like nitrogen, sulfur, and oxygen become protonated [ 63 ]. This was confirmed by MOF1 which was physically adsorbed on Al surface due to this might get adsorbed onto Al surface by van der Waals force to form a protective film to isolate Al from corrosion.…”

Aluminum corrosion inhibitors “{[CuI (CN)2(phen) CuII (CN)2(phen)]5H2O},(MOF1) and {[CuI(CN)2(phen)CuII(CN)2(phen)]5H2O}@TiO2 (MOF1@TiO2) were studied in one molar HCl solution”. The ML results for three different temperatures (25–45 °C) were compared with the results of PDP and EIS analyses. The adsorption of inhibitors on Al surfaces has been calculated and discussed by a Langmuir isotherm. The inhibitors that were created showed great effectiveness, with a noticeable increase in their inhibitory efficiency as the dosage was raised and the temperature was lowered. Inhibition efficiency each amounted to 88.6%, 84.5% at 400 ppm and 25 °C for MOF1@TiO2 and MOF1, respectively. Analyzing the polarization curves of synthesized inhibitors revealed that they were mixed-type inhibitors. Al was found to be surface inhibited when coated with a thin film of inhibitors, and “Al's surface morphology was assessed by different techniques such as scanning electron microscopy (SEM), energy dispersive X-ray (EDX) and atomic force microscope (AFM)”. “Theoretical models like quantum chemical and molecular dynamics simulation authenticated the experimental observation”. The MOFs exhibit exceptional corrosion resistance against Al when exposed to acidic environments, according to several tests.

Natural and fragrant compounds, essential oils (EOs) extracted from plants through hydrodistillation, are gaining popularity as eco-friendly and sustainable agents to protect metals and alloys from corrosion in acidic environments. This research focused on extracting and characterizing an EO obtained from the Cuminum cyminum (CC) plant native to India. The study aimed to evaluate the inhibitory properties of this EO on mild steel in a 0.5 M HCl solution at different concentrations. Various analytical techniques, including potentiodynamic polarization curves, electrochemical impedance spectroscopy, optical microscopy, infrared spectroscopy, and proton magnetic resonance, were employed to assess the effectiveness of this EO extract. Our findings indicate that the Cuminum cyminum L (CCL) extract effectively reduces the corrosion of mild steel in hydrochloric acid with an inhibition efficiency ranging from 79.69 to 98.76%. The optimal inhibition concentration was 2 g/L of EO, and surface analysis confirmed the formation of a protective layer. Furthermore, our results suggest that the inhibitor binds to the metal surface through a charge-transfer process, creating a protective film. Finally, we utilized theoretical calculations and molecular dynamics simulations to elucidate the inhibition mechanism on both a global and local scale.

“…Copper is highly regarded as a key metallic material, celebrated for its outstanding electrical, thermal, and mechanical properties. 1 It is crucial across various sectors, including military, transportation, electronics, automotive, marine, and construction, where its alloys are indispensable in numerous applications. [2][3][4] However, despite its impressive qualities under normal conditions, copper is susceptible to corrosion in severe environmental conditions, especially in acidic contexts containing chloride and sulfate ions.…”
