The corrosion of metals is very important, both economically and environmentally, and is a serious concern. Since the past decades, traditional (chemical) corrosion inhibitors to prevent corrosion have been and are still being used. Although these inhibitors can be said to be a good choice among other protection techniques because of their good efficiency, the toxicity of many of them causes environmental problems, and, due to the change in the laws on the use of chemicals, many of them are no longer allowed. Hence, during the past years, research on green corrosion inhibitors (GCIs) increased and very favorable results were obtained, and now they are very popular. It can be said that biodegradability and easy preparation are their most important factors. Meanwhile, the use of plants, especially their extracts, has been studied a lot. Plant extracts contain compounds that have anti-corrosion properties. In this review, the use of plants as GCIs is investigated, focusing on recent advances in their use. Also, the phenomenon of corrosion, corrosion protection (including coatings, nanoparticles, and chemical inhibitors), and other GCIs are briefly reviewed.

“…[6,10,11] Organic inhibitors have heteroatoms (nitrogen, oxygen, sulfur and phosphorus) and pi-conjugated systems responsible for their corrosion inhibition mechanism. In fact, they act by an adsorption mechanism on the surface of metals and alloys through these electron-rich sites, forming a protective barrier against aggressive agents present in the solution and preventing oxidation of metals and alloys [12][13][14][15][16].…”

In order to investigate the corrosion of carbon steel (C38) in acidic media, experimental studies (weight loss measurements, electrochemical methods, thermodynamic adsorption isotherms and field emission scanning electron microscopy coupled with energy dispersive X-ray) and computational approach were adopted to study the newly synthesized and simple Schiff base structure, namely 4-((phenylimino)methyl) phenol (PIMP) as a corrosion inhibitor for C38 steel in 1M HCl. Characterization techniques (Fourier Transform Infrared spectroscopy, mass spectrometry, proton nuclear magnetic resonance) showed that PIMP was successfully synthesized with a yield of 63%. Experimental methods (weight loss, open circuit potential (OCP), electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP)) showed that PIMP is a mixed-type inhibitor with an inhibition percentage of 91.1% under optimal conditions (7.5 mM PIMP at 30°C). These experimental results were supported by surface analysis (Field Emission Scanning Electron Microscopy (FESEM) coupled with Energy Dispersive X-Ray (EDX)), where PIMP molecules are adsorbed on the steel surface and form a protective barrier against aggressive ions, thereby limiting steel oxidation. The adsorption of PIMP on the carbon steel surface followed the Langmuir adsorption isotherm along with a mixture of physical and chemical adsorption, forming a complete and dense protective film on the C38 steel surface. Theoretical results using density functional theory (DFT) calculations showed that PIMP contains highly reactive centers and confirmed the experimental results obtained.

Corrosion threatens materials in diverse industries, necessitating sustainable corrosion inhibitors. Polysaccharides, abundant natural polymers, emerge as eco‐friendly corrosion inhibitors. This review explores polysaccharides' efficacy, mechanisms, and applications. It introduces the significance of corrosion and the vital role of inhibitors, positioning polysaccharides as promising green solutions. The exploration covers polysaccharide diversity, sources, and eco‐friendly attributes. Corrosion mechanisms are detailed, setting the stage for understanding inhibition strategies. Polysaccharides, with unique adsorption and film‐forming properties, are effective inhibitors, elucidated through electrochemical studies. Influential factors like pH, temperature, and concentration effects, along with practical applicability considerations, are examined. Real‐world implementations across industries underscore polysaccharides' versatility, often surpassing traditional inhibitors. Despite challenges, this review outlines their promising role, addressing concerns and proposing future directions. Polysaccharides emerge as eco‐friendly alternatives, illuminating inhibitive properties, mechanisms, and practical applications, guiding continued research for sustainable corrosion prevention.
