“…The last few decades have witnessed a tremendous interest in the self‐assembled monolayers (SAMs) of organic molecules on the surface of coinage metals 1–3, in particular on Au(111) 4–7 because of their potential application in various interfacial phenomena, such as wetting 8, 9, adhesion 10, 11, and catalysis 12, 13. Also in many corrosion studies SAMs were employed as a protection layer against electrochemical reactions on metal surfaces, due to their pronounced blocking properties 14–17.…”

The electroreduction of oxygen on self-assembled monolayers (SAMs) of various pyridinedisulfides and pyridinethiols on Au(111) surfaces has been investigated in alkaline solutions. Electrochemical experiments that were carried out in threeelectrode cell reveal a good correlation between the chainlength of thiol molecules and the oxygen reduction inhibition of the resulting adlayer films. The effect of retarded diffusion of oxygen through the protective film has been investigated by forming additional layer of immobilized cytochrome c (cyt.c) metalloprotein on pyridine moiety during linear sweep voltammetry (LSV) scans. At sufficiently negative cathodic potentials the electrochemical reaction rate has been observed to increase together with the density of defects. Morphological changes at different levels of cathodic polarization were investigated by ex situ scanning tunneling microscopy (STM), indicating oxygen reduction reaction (ORR) induced structural defects at the metallorganic interface.

“…Thin films and monolayers of molecules adsorbed to surfaces have generated sustained interest due to applications in fields such as molecular and biomolecular recognition [1], corrosion protection [2] and patterning [3]. Alkanethiols are the most studied class of compounds for thin films on gold as they readily bind to the surface and the molecules may form ordered surface structures [4].…”

Thin films of ruthenium phthalocyanine complexes

Four new ruthenium phthalocyanine complexes bearing axial ligands with thioacetate groups that facilitate thin film formation on gold surfaces are presented. STM images and surface coverage data obtained by solution inductively coupled plasma mass spectrometry (ICP-MS) experiments show that peripheral and axial ligand substituents on the complexes have a significant effect on their surface coverage. A laser ablation ICP-MS technique is described here for the first time that provides information about thin films across macro-sized areas. Using the technique, the maximum surface coverage of a ruthenium phthalocyanine complex was found to occur within one minute of gold substrate immersion in the complex-containing solution.

“…A feasible method to reduce the corrosion damage is by coating the metal with a stable and anticorrosive layer. Nevertheless, those traditional protective coatings, including organic layers [ 2 , 3 , 4 ], polymers coating [ 5 , 6 ], oxide layers [ 7 ], and inert metals [ 8 ] have their limitations. For example, the high thickness is necessary for traditional anticorrosive layers to ensure protective effects [ 9 , 10 , 11 , 12 ].…”

Due to the excellent chemical inertness, graphene can be used as an anti-corrosive coating to protect metal surfaces. Here, we report the growth of graphene by using a chemical vapour deposition (CVD) process with ethanol as a carbon source. Surface and structural characterisations of CVD grown films suggest the formation of double-layer graphene. Electrochemical impedance spectroscopy has been used to study the anticorrosion behaviour of the CVD grown graphene layer. The observed corrosion rate of 8.08 × 10−14 m/s for graphene-coated copper is 24 times lower than the value for pure copper which shows the potential of graphene as the anticorrosive layer. Furthermore, we observed no significant changes in anticorrosive behaviour of the graphene coated copper samples stored in ambient environment for more than one year.
