“…Generally, the persistence of inhibition efficiency for green corrosion inhibitors is not desirable, mainly attributing to the instability of corrosion inhibitors and their adsorption film (Chaubey et al, 2021;Salleh et al, 2021). To evaluate the long-term corrosion resistance of PLE and KI, EIS was carried out to in situ monitor their inhibition efficiency on carbon steel under different immersion time shown in Figure 6.…”

“…Considering the threat caused by corrosion with economic, material conservation and safety impacts in various engineering applications, the public have developed several proper corrosion prevention methods, including coating, corrosion inhibitor, sacrificial anode, corrosionresistance alloys, etc. (Nazeer and Madkour, 2018;Wan et al, 2021a;Kang et al, 2021;Salleh et al, 2021;Xu et al, 2021;Cao et al, 2022). Generally, metals are defenceless to corrosion in the presence of acid, which can attack and dissolve metal into ions.…”

The parsley extract (PLE) was prepared using absolute ethyl alcohol. The PLE and synergistic iodide were firstly utilized as efficacious corrosion inhibitors to slow down the corrosion rate of carbon steel-Q235 in 0.5 mol/L H2SO4 solution. The anti-corrosion performance was researched by weight loss method, electrochemical tests, surface analysis and quantum chemistry calculation. Results of electrochemical and weight loss tests show that the synergetic PLE and I− exhibit the optimal corrosion inhibition efficiency 99%. The combined inhibitor displays the favorable long-term corrosion inhibition effect, and the inhibition efficiency can maintain more than 90% after 144 h immersion. The introduction of I− makes carbon steel surface with higher negative charge amount, which could be beneficial to the interaction between corrosion inhibitor and Fe atoms. The adsorption behavior obeys the Langmuir isotherm adsorption, and involves chemical and physical adsorption. On the basis of electrochemical consequences and theoretical calculation, the adsorption process and anti-corrosion mechanisms are further explored.

“…Corrosion is a detrimental and ubiquitous issue in many technological realms such as the marine industry, transportation, and electronic manufacturing, which immensely shortens the lifespan of metals (e.g., copper) and causes economic loss; therefore, it has been attracting numerous targeted investigations all along. − Hitherto, persistent endeavors are engaged in impeding the metal corrosion, and many strategies have been developed such as appropriate structure design, electrochemical protection, application of coatings, and corrosion inhibitors. − One of the beneficial methods to mitigate copper corrosion in aggressive media is the employment of corrosion inhibitors . Numerous synthetic compounds possessing heteroatoms (O, N and S, etc.…”

“…The peel of Chinese yam (CYP) is usually pared and discarded as kitchen garbage before preparing cuisine due to its unpleasant flavor. Fundamentally, CYP possesses different phytochemical constituents (vide infra) of flavonoids, quercetins, and polyphenols which are active anticorrosion components, as reported by screening of common plant extracts. ,,− The anticorrosive capability and the underlying mechanism of the CYP extract (CYPE) have not been clarified for copper in aggressive media, especially the synergetic behavior among different constituents.…”

Active constituents of Chinese yam peel (CYPE), namely, diosgenin (DOG), batatasin-I (BTS-I), batatasin-III (BTS-III), and yam polysaccharide (Y-PS), were extracted via an ultrasonic soaking strategy. The synergetic anticorrosion mechanism among these compounds for copper in artificial seawater (ASW) was clarified by gravimetric measurements, electrochemical evaluations, surface analyses, quantum chemical calculations under a dominant solvent model, and molecular dynamics (MD) simulations. The results of weight loss revealed that CYPE strongly inhibited the corrosion of copper in ASW, and the elevating temperature boosted the anticorrosion efficacy of CYPE. The inhibition efficiency could attain 96.33% with 900 mg/L CYPE in ASW at 298 K due to effective adsorption. CYPE simultaneously suppressed the anodic and cathodic reactions for copper in ASW, which could be categorized as the mixed-type corrosion inhibitor with the predominant anodic effect. Similar electrochemical kinetics was evidenced by electrochemical frequency modulation (EFM). Electrochemical impedance spectroscopy (EIS) indicated that CYPE prominently increased the charge-transfer resistance at the copper/electrolyte interface without altering the corrosion mechanism. Extending the immersion time was also conducive for CYPE to further minimize the corrosion of copper in ASW, which was demonstrated by the time-course polarization, EIS, and EFM tests. Owing to the adsorption of CYPE, the copper surface was well-protected and showed reduced wettability and limited variation of roughness. From the outcomes of quantum chemical calculations, global and local reactive descriptors of DOG implied the cross-linked deposition of actually formed dioscin on the copper surface; otherwise, those of BTS-I/-III showed the propensity for parallel adsorption, which could chemically anchor on the voids uncovered by dioscin and thereby synergistically inhibit the corrosion process. The adsorption orientations of DOG, BTS-I, and BTS-III were also consolidated by MD simulations. The findings of this study might be beneficial to inspire the development of eco-friendly corrosion inhibitors from plant wastes for copper in marine environments.

“…Consequently, corrosion inhibitors, especially organic species, have attracted significant scientific and industrial attention owing to their low cost, convenience and efficiency. 6 Many compounds such as imidazoles, 7 quinolines 8 and amines 9 have been explored as effective corrosion inhibitors for C-steel in various media. However, their low biodegradability, high cost and rigorous synthesis protocols hamper their sustainable application.…”
