Abstract Carbon dots (CDs) have garnered extensive attention owing to their excellent biocompatibility, elevated specific surface area, and facile functionalization, as well diverse methods of preparation. In recent times, CDs been applied for anti‐corrosion obtained some significant results. this work, the preparation are first briefly introduced, relative merits different approaches highlighted. Subsequently, application in realm corrosion inhibitors is discussed, inhibition effects mechanism nitrogen‐doped CDs, nitrogen sulfur‐co‐doped functionalized with other elements nitrogen‐co‐doped summarized. Finally, CD‐modified coatings protective analyzed detail. This review summarizes progress research related heteroatom‐doped applications anticipates prospects protection. With unique properties versatile applications, expected assume a progressively pivotal role advancement cutting‐edge protection technologies.

A green and effective anti-corrosion and anti-microbial inhibitor of citric acid-based carbon dots: Experiment and mechanism analysis

Journal of Materials Research and Technology, Год журнала: 2024, Номер 32, С. 2149 - 2159

Citric acid-based carbon dots (CA-CDs) with different amounts of heteroatoms N were obtained through hydrothermal synthesis method. The microstructure, optical, antibacterial and anticorrosive behaviors systematically analyzed. Through detection, the atoms existed in form pyridine-like N, pyrrole-like graphitic promoted grain coarsening dots. CA-N-CDs displayed obvious pH dependence good stability from optical behavior analysis. ability citric was improved by inserting atom, rate directly proportional to amount which up 95% for E. coli S. aureus. However, anticorrosion showed an initial increase followed a decrease as atom increased, reaching its peak at CA-N12%-CDs. At this moment, corrosion current density (icorr) metal 4.68 × 10−6 A/cm2, decreased 122 times compared blank solution. Meanwhile, inhibition (IE) 96%, mainly depended on tight adsorption surface.

Influence of metal ions on cysteine as a corrosion inhibitor for low carbon steel in sulfuric acid: Polarization, EIS, XPS, and DFT analysis

International Journal of Electrochemical Science, Год журнала: 2024, Номер 19(7), С. 100620 - 100620

This study examines the effectiveness of cysteine as an eco-friendly in inhibiting corrosion low-carbon steel a sulfuric acid solution and impact adding various metal ions (Cu2+, Ni2+, Co2+) to media. All solutions were prepared using distilled water. The results show that 5 mM inhibits (IE = 65%), increasing 93.5% presence 4×10-5 M Cu2+ ions, but decreasing with addition Co2+ or Ni2+ ions. inhibitive action cysteine-Cu is best one may be attributed formation protective coating on surface, which prevents chemical reactions aggressive environment. Moreover, DFT calculation found adsorption energy increased from -17.2 -97.7 -104.6 kcal/mol case cysteine, Cysteine-Cu SAM, Cysteine-Cu(II) Salt closest atom surface reduced 2.576 2.128 2.146 Å indicates better adhere surface. SEM, XRD, XPS used analyze layer. has potential develop new more effective inhibitors for industrial applications.
