“…The FTIR spectrum of ZnONPs-ht exhibits almost similar peaks of spectrum of ZnONPs-po but two differences should be remarked. First difference is the arising of an intensive peak at 550 cm -1 , which is assigned to vibration of C-Br of CTAB [23], which is used as stabilizer. Second discrepancy is the diminishing the intensity of C=O bond, which is due to the absence of carbonyl group in the CTAB structure.…”

Zinc oxide (ZnO) is an inorganic semiconductor compound with a direct band gap of 3.3 eV and is mainly used as additive in many technological applications such as cosmetic, food, and cement. The functionality of ZnO strongly depends on the particle size, crystallinity, and shape. In this work, ZnO nanoparticles (ZnONPs) were prepared using two different routes: polyol and hydrothermal processes. The products were compared using scanning electron microscopy, transmission electron microscopy, X-Ray diffraction, Fourier transform infrared spectroscopy, and UV-Vis. absorption spectroscopy techniques. Additionally, hydrothermal method was performed at three temperature values of 100, 120, and 150 o C and the effect of temperature on the hydrothermal synthesis of ZnONPs was also discussed in this study.

“…9b). This explains that the surface of steel in hydrochloric media is highly porous with oxides formed over it [47,48]. However, it is obvious that the addition of 30 mg/L of extract shows less damage in the surface as compared to blank with water contact angle of 103.1° ± 5.83° demonstrating a hydrophobic character, suggesting the formation of protective film due to adsorption of SA onto the steel surface (Fig.…”

Inhibitory effect of Senecio anteuphorbium as green corrosion inhibitor for S300 steel

The present work proposes the study of the extract of Senecio anteuphorbium (SA) as green corrosion inhibitor. This inhibitory effect of SA extract on the corrosion of S300 steel in hydrochloric acid 1 M has been evaluated by using the potentiodynamic polarization and electrochemical impedance spectroscopy. From the outcome of the polarization curves, SA extract acts as mixed-type inhibitor. The inhibition efficiency increased with the extract concentration increase to achieve a maximum of 91% at 30 mg/L. The adsorption of the inhibitor on the steel surface follows Langmuir isotherm and the values of activation energy suggested that the adsorption of inhibitor is a physical-chemical adsorption. Kinetic parameters such as enthalpy, activation energy and entropy were determined and discussed. The surface morphology of steel was observed before and after adding inhibitor by Fourier transform infrared spectroscopy. The changes in contact angles identified the formation of the protective film. Scanning electron microscopy and energy-dispersive X-ray revealed the adsorption of the same organic compounds of the extract on the interface metal/solution.

The inhibition of corrosion of carbon steel in well water using diethylenetriamine penta (methylene phosphonic acid) (DETPMP), Zinc ions and dodecyltrimethylammonium bromide (DTAB) was investigated using weight-loss measurement, electrochemical polarization and impedance methods. Inhibition efficiency of above ternary inhibitor reaches maximum values at 93 %. The biocidal efficiency of DTAB was studied which reaches maximum of 88 % at 125 ppm DETPMP, 10 ppm Zn 2? and 150 ppm DTAB. The shape of DC polarization profile revealed the new ternary system which acts as anodic type inhibitor. AC impedance spectroscopic studies indicated the formation of a protective film onto the metal surface in the presence of inhibitors. Analyses of the protective film using scanning electron microscope, energy dispersive X-ray analysis, atomic force microscopy and Fourier transfer infrared spectroscopy have revealed that the film consists of Zn(OH) 2 , oxides and hydroxides of iron and the inhibitor molecules in the form of a complex.
