Evaluation and characterization of the symbiotic effect of benzylidene derivative with titanium dioxide nanoparticles on the inhibition of the chemical corrosion of mild steel

Abstract

A new benzylidene derivative, namely 3,, has been synthesized and instrumentally confirmed with Elemental Analysis (CHN), Nuclear Magnetic Resonance (NMR), and Fourier Transform Infrared Spectroscopy (FT-IR). Titanium Dioxide (TiO 2 ) nanoparticles (NPs) were synthesized and characterized by X-ray. The mutualistic complementary dependence of BPTA with TiO 2 nanoparticles as anticorrosive inhibitor on mild steel (MS) in 1.0 M hydrochloric acid has been tested at various concentrations and various temperatures. The methodological work was achieved by gravimetric measurement methods complemented with surface analysis. The synthesized inhibitor concentrations were 0.1 mM to 0.5 mM and the temperatures ranging from 303-333 K. The BPTA with TiO 2 -NP as a synergistic inhibitor becomes superior inhibitive effects with more than 96% inhibition competence of MS coupons in a harsh acidic medium. The efficiency of the inhibition improved with increasing BPTA content and also increase with the Synergistic effects of BPTA with TiO 2 -NP. The excellent effectiveness was performed with the 0.5 mM concentration of BPTA and become higher with adding of TiO 2 -NP rising to the maximum inhibition efficiency (IE). However, the inhibition efficacy declined as the temperature rises. Results of BPTA as corrosion inhibitor indicated the obedience of the adsorption of the inhibitor of mixed type on the surface of MS to Langmuir adsorption isotherm. It was found that the BPTA and performance depend on the Synergistic effects, concentrations of the TiO 2 -NP and BPTA, in addition to the solution temperature. Nevertheless, the quantum calculations have confirmed the direct correlation of the electronic characteristics of BPTA with the corrosive inhibitive influence.

Adsorption, temperature and corrosion inhibition studies of a coumarin derivatives corrosion inhibitor for mild steel in acidic medium: gravimetric and theoretical investigations

“…As in Figure 6, the analysis of frontier orbitals, HOMO and LUMO demonstrate that significant nucleophilic sites attack atoms of coumarin and triazole rings and these heteroatoms have the ability to interact with mild steel surface [51]. HOMO and LUMO are related with the abilities of donating and accepting electrons, respectively.…”

Experimental and Computational Studies of a Novel Metal Oxide Nanoparticle/Conducting Polymer Nanocomposite (TiO2/PVP) as a Corrosion Inhibitor on Low-Carbon Steel in Diprotic Acidic Medium

“…The corrosion behavior of the chitosan/TiO 2 nanocomposite was investigated, and the smoothness and hydrophobicity of the surface were found by contact angle measurement, giving the highest inhibition efficiency of 84.69% on a mild steel substrate in 0.1 N HCl media. 10 There are several studies done on the organic/inorganic/natural extract/polymer nanocomposite such as the olive leaf extract/TiO 2 nanocomposite, 11 Aganonerion polymorphum leaf extract−titania composite, 12 chitosan-doped hybrid/TiO 2 nanocomposite, 13 Ti−Si−B−C nanocomposite, 14 Ni−Ti nanocomposite, 15 polyaniline/ZnO nanocomposite, 16 benzylidene derivative−TiO 2 nanocomposite, 17 ZrO 2 /glycine nanocomposite, 18 etc., which gave much more favorable results in all aspects.…”

Study of the Efficiency of Layered Double Hydroxide-based Corrosion Inhibitors on Mild Steel in Chemical Pickling in HCl Medium

“…On one hand, it is less expensive relative to other alloys and, on the other, it has suitable mechanical characteristics [2][3][4]. Yet, a chemical pickling step is required in its industrialization process to eliminate metallic impurities and standardize its surface [5][6][7][8][9][10]. Hydrochloric acid (HCl) is one of the most widely used agents in the industry for steel pickling, cleaning, etc.…”
