“…In this equation, the R ct(inh) and R ct are the charge transfer resistances in the presence of inhibitor and without inhibitor, respectively. The protective layer results in a decrease in the rate of charge transfer (electron exchange) between metallic surface and the electrolyte and causes an increase in inhibition efficiency 33 , 46 , 47 . Thus, a significant increase in R ct and a remarkable decrease in C dl values in the inhibited solutions compared with the values for samples corroded in blank are observed in Table 2 .…”

A series of 4-ferrcenylbutyl carboxylate esters with different alkyl chain length (C2-C4) of carboxylic acids were synthesized using Fe3O4@SiO2@(CH2)3-Im-bisEthylFc[I] nanoparticles as catalyst and have been characterized with FT-IR, 1H NMR, and 13C NMR. Ferrocenyl-based esters were used as corrosion inhibitors of mild steel in the 1M HCl solution as corrosive media. The corrosion inhibition efficiency of the synthesized ferrocenyl-based esters has been assessed by electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), atomic force microscopy (AFM), and scanning electron microscopy (SEM). The 4-ferrocenylbutyl propionate showed a more effective corrosion inhibition behavior among the studied esters with 96% efficiency after immersion in the corrosive media for 2 weeks. The corrosion inhibition mechanism is dominated by formation of passive layer of inhibitor on the surface of the mild steel by adsorption. Moreover, the adsorption characteristics of 4-butylferrcenyl carboxylate esters on mild steel were thoroughly explored using density functional theory calculations. It was found that the Fe atoms located around the C impurity in the mild steel are the most efficient and active sites to adsorb 4-butylferrcenyl carboxylate esters.

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.
