“…From the FTIR, ASPE had chemical functional groups that served as a green corrosion inhibitor. With similar results, Gusti et al, 2019 [21], concluded that the obtained compound from avocado seed was rich in polysaccharides, due to its functional groups, with a small quantity of tannin, among other compounds. Consequently, the derived inhibitor from avocado seed possibly contained nitrogen and oxygen atoms (Figure 8) in the aromatic ring and the functional group, which are generally found in other corrosion inhibitor structures with high inhibitory properties [25].…”

“…Avocado seed contains aromatic rings and heteroatoms, indicating that it can be used as a high-performance and sustainable corrosion inhibitor. Other researchers have also reported the influence of avocado oil and seed for other materials [20][21][22][23][24][25]. Thus, this study was designed to study the potential of avocado seed extracts as a green corrosion inhibitor that is environmentally friendly, nontoxic, and cheap for API 5L X65 steel usually used for pipelines in 1 M H 2 SO 4 solution.…”

Currently, the use of synthetic inhibitors in preventing corrosion is destructive to the environment; therefore, natural inhibitors might be an alternative and innovative solution to this challenge, owing to their sustainability. Herein, wasted avocado seed extract was examined as a sustainable and green inhibitor for API 5L X65 pipeline steel at an ambient temperature using the gravimetric analysis, the potentiodynamic polarization curve, and linear polarization resistance techniques. The inhibitor’s chemical characterization was carried out with Fourier-transform infrared spectroscopy (FTIR), and the morphological characterization was carried out by detailed scanning electron microscopy and energy-dispersive X-ray spectroscopy (SEM/EDX). The result showed that the extract decreased the corrosion rate by retarding the cathodic and anodic electrochemical reactions, with a maximum efficiency of 88% at 5 g/L. The extract was adsorbed physically onto the X 65 steel following the Langmuir adsorption isotherms. The electrochemical studies showed that the agro-waste was a mixed-type inhibitor. The SEM image of the X65 steel with the extract showed thin film formation on the steel surface. The extract can be substituted for synthetic inhibitors, which are toxic, scarce, and costly.

“…Avocado seeds are recognised to contain various bioactive and functional substances, which are important features as corrosion inhibitors. However, inadequate management of this waste, which is generated in significant amounts and sometimes disposed of by burning or indiscriminate disposal, can lead to environmental nuisances and pollution [33,34]. Therefore, researchers have started to use avocado seeds as corrosion inhibitors because they form a protective oxide film on various components (especially steel) against corrosion [33][34][35].…”

There is currently a high need for effective and nontoxic corrosion inhibitors in the acidising industrial process due to rising concern for human life and environmental sustainability. As a result, in this work the anticorrosive efficiency of avocado seed nanoparticle extract (ASN) in APIX65 pipeline steel corrosion was examined in 1M HCl medium through weight loss and the potentiodynamic polarisation approach. The inhibitor morphology, particle size, and elemental composition were investigated using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and energy-dispersive X-ray spectroscopy (EDX). The SEM examination of the steel surface indicates a considerable difference, demonstrating that the inhibitor formed a protective barrier on the metal surface with heteroatom constituents from the inhibitor. The findings show a corresponding increase in inhibition efficiency as the inhibitor concentration increases, with the highest inhibitor efficiency found at 95.65% for 5 g of ASN in 1 M HCl solution. Regarding the electrochemical test, ASN performs as a mixed-type corrosion inhibitor. The weight loss test findings corroborated the electrochemical investigations, indicating that ASN had a high inhibitive effect on X65 steel in an acid medium. The ASN nanosize gives a huge surface area, resulting in increased reaction activity and the development of more shielding coatings. This study sheds light on the development of sustainable corrosion inhibitors for X65 steel.

“…To increase the activity of the AS-SAM films formed over the copper electrode for methanol electrooxidation reaction, Ni particles, which have good methanol activity, [45,49,50] were precipitated over the Cu/AS-SAM surface. For this aim, the Cu/AS-SAM electrode was dipped into a Ni deposition bath (1% NiCl 2 .6H 2 O).…”

“…AS contain functional molecules that have not been properly evaluated but such as tannin, flavonoid saponin, quinone, tannin, terpenoid, and starch. [45,46] In this context, corrosion researchers are making efforts to develop these non-toxic and economically obtained environmentally friendly compounds as corrosion inhibitors, which are contained in a waste that cannot be reasonably evaluated, such as the AS. The components in the avocado seed are indicated in detail by Indatri et al [47] Therefore, avocado fruits and their wastes have been used in different applications.…”

Catalysts are important equipment that limits the performance of direct methanol fuel cells (DMFC). With the use of appropriate electrocatalysts, the efficiency of DMFC can be increased. Although the platinum-based catalysts have high efficiency for this process high cost and its limited sources on the earth are the main drawbacks. On the other hand, platinum affectivity may be alternative material due to its high resistance against CO-poisoning on the electrode/solution interface. They have also a low cost. In this study, the extracts of avocado seed (AS) are prepared in ethanol solvent and their self-assembly monolayer (SAM) films were prepared on the copper specimens (Cu/AS-SAM). The AS-SAM film modified catalyst was used as anode material for electrooxidation of methanol in an alkaline solution. To increase catalytic efficiency, the surface of Cu/AS-SAM was modified by electrodeposition of Ni. The surfaces of the bare copper, the AS-SAM film, and the Ni-modified were described by SEM, AFM, and EDX-mapping measurements. Their electrocatalytic activity and stability were evaluated with 1.0 M methanol containing alkaline solution by cyclic voltammetry (CV), Tafel curves and chronoamperometry (CA) tests. The results showed that a durable and homogeneous AS-SAM film forms on the copper surface from the extracts of AS in ethanol solvent. The AS-SAM film is electroactive for the methanol electrooxidation reaction. Moreover, modification of the film by depositing with Ni enhances its activity. The AS, agriculture waste can be utilized for fabricating anode materials for methanol electrooxidation reactions.
