“…It was shown that the rate of steel corrosion increased with temperature for a particular OPE and OPE-CuO NPs concentration. Additionally, the outcomes obtained showed that the investigated OPE had an inhibitory effect at the evaluated temperatures, and that the extract inhibitor's efficiency was temperature-dependent, and that the percentage decreased as the temperature increased due to physisorption [53][54][55].…”

The effectiveness of onion peel extract, (OPE), for carbon steel in one molar (1 M) hydrochloric acid solution was illustrated utilizing weight loss (WL) techniques, potentiodynamic polarization (PDP), electrochemical impedance spectroscopy (EIS), and surface morphological examination. Also, this process was characterized using Fourier transform infrared (FT-IR), energy dispersive X-ray spectroscopy (EDX), thermogravimetric analysis (TGA), atomic force microscopy (AFM), and scanning electron microscope (SEM). The protective efficiency rises as OPE concentration rises and decreases with corrosive solution temperature, according to weight loss measurements. Polarization curves display that OPE behaves as a mixed-type inhibitor in hydrochloric acid. The adsorption process mechanism is supported by EIS, which demonstrates that charge-transfer resistance rises, and double-layer capacitance falls with inhibitor concentration. OPE adhering to carbon steel follows the Langmuir isotherm, through a physical adsorption process and the inhibitor molecules were shown to have spontaneously adsorbed onto the carbon steel based on the negative values of Gibb's free energy of adsorption. The synergistic effect of copper oxide nanoparticles, CuO-NPs in combination with OPE on the inhibition corrosion of carbon steel was evaluated. The results showed that the inhibition efficiency of OPE increases in the presence of CuO-NPs due to synergistic interactions of OPE extract molecules with CuO-NPs. The electron-donating capacity of the chemical component of the OPE has been shown in theoretical studies employing quantum chemistry methods.

In this study, coupled titanium dioxide-silver composite and steel electrode pairs were investigated for their use in cathodic protection under illuminated and dark conditions to prevent corrosion and enhance contaminant degradation under photocatalysis. A series of photoelectrochemical tests were used to determine the properties of the photoanode and identify the cathodic protection behaviour in the presence and absence of organic/inorganic contaminants. Additionally, corrosion-prone steel was used to test the principle of photocathodic protection in reducing oxide formation and mass loss under base metal and welded materials.
