“…It was discovered that all inhibitors reduce corrosion rate to a significant extent which is as a result of adsorption of organic molecules on metallic surface. Mostly N and O of alkaloids are responsible for the adsorption according to [2], [24][25][26][27][28]. The corrosion inhibitors function by complex formation of the molecule with the metal ion, which remains in a solid state.…”

The research investigated the effect of silver nanoparticles on the corrosion behaviour of Mild steel and 316 Austenitic stainless steel in 0.5M H2SO4 using the potentiodynamic polarization method. The nanoparticles were synthesized from the sweet potato (Ipomoea batatas) plant extracts using Silver Nitrate (AgNO3) and were characterized using Atomic Adsorption Spectroscopy, Fourier Transform Infrared Spectroscopy and the Ultraviolet Visible Spectroscopy Technique. The AAS results showed that the plant extract is eco-friendly as it does not contain heavy metals. The FTIR results showed the different functional groups present in the extracts obtained from the different parts of the plant to be Alcohol O-H, Nitrile C≡N, Alkyne C≡C, Alkene C=C and Benzene Ring C=C. The UV-Vis results showed the presence of phenolic compound which aided inhibition. The results from the potentiodynamic polarization showed that the nanoparticle obtained from the leaf has the highest corrosion inhibition efficiency and the corrosion inhibition efficiency increases as the concentration of inhibitors increases.

“…Titanium di oxide being a ceramic material at its nano level with tuned physical and chemical properties have been employed widely in self-cleaning [2], UV protection [3], photo catalysis [4], self sterilizing and corrosion inhibition [5]. The reduced size of the titania nano particles have shown a prominent impact on its corrosion resistance [6] and also customized morphological properties through templates enhanced the expected results [7]. Normally the corrosion of steel, brass appliances has been controlled by chromium protective coatings quite successfully.…”

In recent days synthesis and structuring of intelligent nano materials investigated and reported has developed critical scientific ideas to the greater extent. The excellent thermal, optical and electrical properties along with its resistant to corrosion, wear, oxidation and erosion made it unique for sustainable environmental applications. Here nano structured Titanium di oxide particles synthesized from its precursor via template assisted sol-gel technique have been verified as corrosion inhibitor of brass alloy in acid medium along with its photo catalytic and anti-microbial applications. The physico-chemical parameters of the synthesized nano materials were studied using XRD, FT-IR, UV-DRS, SEM, TEM and BET analytical techniques and revealed the impact of tea leaf extract as a template in producing a nano catalyst NTG about 14 nm in size with tailored structural, optical and morphological characteristics. The rate of corrosion of a brass strip in acid medium is verified by weight loss method and the inhibitor efficiency increased with the increase in concentration of the nano catalyst. The catalytic activity is proved against the photo degradation of a toxic melamine, a trimer of cyanamide. The synthesized nano catalyst showed excellent antimicrobial properties proven against the growth of K. pneumonia and H. influenza.

“…There are reports in the literature showing that the immobilization of TiO 2 nanoparticles in Si-based films has demonstrated the potential for degradation of organic pollutants in gas and liquid phase 4 . In the area of biomaterials, SiO 2 -TiO 2 nanostructures have been evaluated as alternatives to make the surface less receptive to biological cultures (bacteriostatic), or more detrimental to them (bactericides), a fact that avoids the inconveniences generated by the growth of biofilms on the implant surfaces 5,6 . There are also applications related to the protection of metal surfaces against corrosion.…”

Recently, there has been growing interest in the incorporation of particles in plasma deposited thin films to creation of multifunctional surfaces. In this work a new hybrid methodology based on the plasma enhanced chemical vapor deposition (PECVD) of hexamethyldisiloxane combined to the reactive sputtering of TiO 2 is proposed for the preparation of SiO x C y H z -TiO 2 composite films. Specifically, the effect of the proportion of O 2 in the plasma environment on the morphology, chemical structure, elemental composition, wettability, thickness and surface roughness, of the films was studied. Agglomerates of TiO 2 (16-83 μm) were detected into the organosilicon matrix with the concentration of particulates growing with the percentage of oxygen in the feed. In general, there was elevation in the angle of contact of the surfaces as the oxygen supply increased. Interpretation is proposed in terms of the influence of the oxygen supply on the TiO 2 sputtering rate and in the oxidation of plasma species.
