To explore the slow-release potential of indole oxygen-containing functional group derivatives in acidic media order to reduce their negative impact on environment. We investigated corrosion inhibition effect 5-Methoxy-indazole (MIA) and Methyl 1H-indazole-5-carboxylate (MIC) copper H2SO4 through electrochemical testing, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) analysis, theoretical calculations. Research has found that MIA MIC exhibit excellent performance, with achieving an efficiency up 91.04%. SEM observed formed a protective film surface, effectively isolating corrosive medium. The adsorption behavior conforms Langmuir model, indicating coexistence chemical physical adsorption. Density theory calculations (DFT) molecular dynamics simulations (MD) further revealed mechanism imidazole derivatives, emphasizing for application media. These results not only elucidate compounds, but also provide new ideas control environments.

The coexisting anticorrosion and antibacterial functions are of great significance for the marine industry. Controllable surface negative charge wettability pyrrolic nitrogen-doped carbon dots (NCDs) derived from single antibiotic norfloxacin precursor with a special nitrogen heterocyclic structure were successfully fabricated through hydrothermal route. incorporated functional groups chemical bonds, charge, mechanism pyrrole ring formation at molecular level, properties NCDs revealed by FTIR, XPS, zeta potential, LC-MS, electrochemical techniques. present corrosion efficiency (96.1%) in 3.5 wt % NaCl saline solution presence air N2 or UO22+ is higher than most previously reported values. proposed electron transfer suggests that domains strengthened saltwater sink effect to repel chlorine simultaneously large number electrons injected into copper as reservoir based on energy-level matching, thereby avoiding Cu0 oxidization. Current works provide guideline exploring novel eco-friendly highly efficient NCD inhibitor materials safeguarding metals seawater.
