“…The performance of an inhibitor can be predicted using its E HOMO , E LUMO , and ∆E values. The tendency of the inhibitor molecule to contribute electrons to the metal surface is correlated with E HOMO , while E LUMO is used to explain the ability of inhibitor molecules to obtain electrons from the metal surface [43]. Inhibitors with higher E HOMO values show a high propensity to donate electrons to the metal surface of the unoccupied d-orbital [44].…”

Extracts from plant materials have great potential as alternatives to inorganic corrosion inhibitors, which typically have harmful consequences. Experimental and theoretical methodologies studied the effectiveness of agricultural waste, namely, date palm seed extract as a green anti-corrosive agent in 0.5 M hydrochloric acid. Experimental results showed that immersion time and temperature are closely related to the effectivity of date palm seed as a corrosion inhibitor. The inhibition efficiency reduced from 95% to 91% at 1400 ppm when the immersion time was increased from 72 h to 168 h. The experimental results also indicated that the inhibition efficiency decreased as the temperature increased. The presence of a protective layer of organic matter was corroborated by scanning electron microscopy. The adsorption studies indicated that date palm seed obeyed Langmuir adsorption isotherm on the carbon steel surface, and Gibbs free energy values were in the range of −33.45 to −38.41 kJ·mol−1. These results suggested that the date palm seed molecules interacted with the carbon steel surface through mixture adsorption. Theoretical calculations using density functional theory showed that the capability to donate and accept electrons between the alloy surface and the date palm seed inhibitor molecules is critical for adsorption effectiveness. The HOMO and LUMO result indicated that the carboxyl (COOH) group and C=C bond were the most active sites for the electron donation-acceptance type of interaction and most auxiliary to the adsorption process over the Fe surface.

“…Besides essential oil, some of corrosion inhibitors derived from plant extracts [12,13,[60][61][62][63][64][65][66][67][68][69][70][71][72][73][74][75] with the major components worthy for inhibition are shown in Table 2. For instance, the investigation of mild steel protection in 0.5 M sulphuric acid indicates that phytochemicals (methoxypyrazine, wine lactone and bisphenol A) found in the extracts of Armoracia rusticana [60] are responsible for its inhibition performance.…”

Considering the fact that corrosion of metals and alloys presents a significant problem all over the world, the one of most recently utilized approaches to combat this problem necessitates the researches for employment of new materials, which satisfied the green chemistry idea. In this connection, the development of sustainable corrosion inhibitors is highly demanded due to the increasing of awareness of green chemistry principles not only in corrosion discipline, but also in all branches of science and technology. Due to natural and biological origin as well as their eco-friendly extraction, the plant materials and biomass derived from various waste sources could be applied as beneficial substances for metals and alloys protection in different corrosion environment. Therefore, this work reports the main findings regarding their employments as green anticorrosion substances.

“…Ficus tikoua leaves and Euphorbia falcate extract were used as an eco-friendly corrosion inhibitor for carbon steel in HCl media. [13][14][15] Lignin, black pepper and castor seeds have been shown to be effective inhibitors of steel in acidic medium. [16] Prickly pear seed oil (Opuntia Ficus -indica L.), chamomile essential oil, argan oil and Mentha Spicata oil were identified and reported as potential corrosion inhibitors of steel, their effectiveness reached 97 %.…”

Phenolic compounds in Tunisian wild Rhus pentaphylla fruits during two maturity stages are identified by LC-MS-ESI. The corrosion inhibition efficiency of their extracts was analyzed by the use of polarization curves and electrochemical impedance spectroscopy. The qualitative analysis highlighted the presence of 11 phenolic compounds in total (3 phenolic acids and 8 flavonols) for the un-ripe stage (S1), 7 compounds (1 phenolic acid and 6 flavonols) have been identified for the fully-ripe stage (S2). The electrochemical behavior analysis of carbon steel in (1 M) HCl medium showed a maximum inhibition efficiency of 45.49 % was achieved by using 100 ppm of the inhibitor. Polarization studies indicate that the extracts act as a mixed inhibitor. As well, it has been shown that the first stage presents the highest inhibitory efficacy compared to the second. These results confirm the good correlation between the phytochemical composition and corrosion inhibition capacity.
