“…This ternary oxide has been widely used because of its outstanding properties and potential scientific and technical applications [17]. ZnTiO 3 has been investigated in a variety of applications as an antibacterial, catalyst, nanofiber, white pigment, microwave dielectric, gas sensor, nonlinear optical, corrosion inhibitor, and luminescent material [18][19][20][21][22][23], but its application in adsorption has not been sufficiently studied, despite the fact that the literature indicates that due to its great specific area, it could have an important potential as an adsorbent [24,25]. ZnTiO 3 is a polar oxide of the LiNbO 3 -type (LN-type) with both cations coordinated octahedrally in a three-dimensional framework of the octahedron perovskite (Pv) that shares corners [26].…”

The search for alternative materials with high dye adsorption capacity, such as methylene blue (MB), remains the focus of current studies. This computational study focuses on oxides ZnTiO3 and TiO2 (anatase phase) and on their adsorptive properties. Computational calculations based on DFT methods were performed using the Viena Ab initio Simulation Package (VASP) code to study the electronic properties of these oxides. The bandgap energy values calculated by the Hubbard U (GGA + U) method for ZnTiO3 and TiO2 were 3.17 and 3.21 eV, respectively, which are consistent with the experimental data. The most favorable orientation of the MB adsorbed on the surface (101) of both oxides is semi-perpendicular. Stronger adsorption was observed on the ZnTiO3 surface (−282.05 kJ/mol) than on TiO2 (–10.95 kJ/mol). Anchoring of the MB molecule on both surfaces was carried out by means of two protons in a bidentate chelating (BC) adsorption model. The high adsorption energy of the MB dye on the ZnTiO3 surface shows the potential value of using this mixed oxide as a dye adsorbent for several technological and environmental applications.

“…The percentage inhibition efficiency (η%) can also be calculated by corrosion rate values, and it is given as η ( % ) = false( CR false) normalo − false( CR false) normali false( CR false) normalo × 100 where (CR) o and (CR) i indicate the corrosion rate in the absence and presence of the inhibitor, respectively.…”

The titanium dioxide/poly(vinylpyrrolidone) (TiO2/PVP) nanocomposite was prepared by in situ polymerization using different concentrations of poly(vinylpyrrolidone). The titanium dioxide nanoparticles were synthesized by a co-precipitation method using titanium tetraisopropoxide (TTIP) and ethanol (C2H5OH). The particle size of the synthesized TiO2 nanoparticles and TiO2/PVP nanocomposite was determined through the X-ray diffraction (XRD) technique, and ultraviolet–visible (UV–vis) and Fourier transform infrared (FT-IR) spectroscopy and scanning electron microscopy/energy dispersive X-ray (SEM/EDAX) were used to characterize the synthesized nanoparticles (NPs) and nanocomposite (NC). The corrosion inhibition of low-carbon steel in 0.5 N sulfuric acid (H2SO4) by titanium dioxide nanoparticles, poly(vinylpyrrolidone), and their nanocomposite was investigated by gravimetric and electrochemical methods. According to the results of potentiodynamic polarization curves and alternative current (AC) impedance analysis, all inhibitors followed mixed-type inhibition and formed a monolayer on the surface. The gravimetric study demonstrated that all the investigated inhibitors followed Langmuir monolayer adsorption. Experimental data from atomic force microscopy (AFM) and quantum chemical analysis also showed that the protective film developed by the prepared nanocomposite exhibited excellent corrosion resistance that was superior to that of other microconstituents.

“…The traditional metal anticorrosion methods mainly include electrochemical protection, coating and electroplating, etc. (Sowmyashree et al, 2021). At present, the metal corrosion inhibitors are widely employed to protect metals due to their effectiveness (Brycki & Szulc, 2021) .…”

Surfactants play an important role in the domain of metal anticorrosion. Gemini surfactants, as corrosion inhibitors, have the advantages of strong practicality, high safety, convenient operation and fast response. In this study, a new Schiff‐base cationic Gemini surfactant (named TMPA) was designed, synthesized and characterized. The mechanism of metal anticorrosion of surfactant was studied by electrochemistry and static weightlessness method. And the adsorption isotherm of TMPA shows that the behavior follows Langmuir adsorption isotherm. The anticorrosion efficiency of printed circuit board (PCB) was 92.88% and Q235 carbon steel (Q235 CS) was 97.78% with the addition of only 5 mM TMPA. The surface appearance of the PCB and Q235 CS was scrutinized by x‐ray photoelectron spectroscopy and scanning electron microscopy, proving that samples have few corrosion marks in the presence of TMPA and oxidants. These results show that TMPA provides an attractive application in terms of metal corrosion inhibition.
