Nickel-zinc tungstate nanocomposites deposited on copper surface for corrosion protection in chloride solution

Amorphous cobalt–nickel borides boost electrocatalytic ethanol oxidation coupled with energy-saving hydrogen production

“…27 Besides, the binding energy corresponding to Ni-B in NiCoB@NiCoWO 4 negatively shifts compared with NiCoB, implying that the addition of tungsten can regulate the electronic properties of Ni. 36 Similarly, in addition to the peaks of Co 3+ and Co 2+ , a new peak for Co-B at 777.8 eV is observed in the high-resolution XPS spectrum of Co in NiCoB@NiCoWO 4 (Fig. 2d).…”

Nitrogen–Sulfur Codoped Ti3C2Tx MXene as a Corrosion Inhibitor for Copper in a Chloride Environment: Electrochemical and Computational Studies

“…As presented in Figure a, all of the Nyquist curves evidence a single capacitive arc in the high-frequency area and a continuous straight line in the low-frequency tail area. The depressed semicircles at the high-frequency area is attributed to the charge-transfer phenomenon, while the presence of a straightforward line at the low-frequency tail region describes the diffusion concept (Warburg). , The Warburg effect ( W ) is attributed to either the diffusion of dissolved Cu 2+ in the solution or oxygen at the Cu/solution interface . In this aspect, competition usually exists between the oxygen gas and the inhibitor molecules on the Cu surface.…”

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

“…These nanoparticles are responsible for the barrier strength, which assists to organize and connect with the polymer chain that helps boost the film's spreading and coverage. 54 The efficacy of the nanocomposite was increased, demonstrated by weight loss measurements, indicating that it was adsorbed on the low-carbon steel substrate more efficiently and covered the surface-active sites and thus significantly reduced the rate of corrosion. 55 The NC tends to protonate in acidic solutions since the corroded low-carbon steel surface has a positive surface charge.…”

“…The NC helps increase adhesion, rigidness, and compactness, thus providing more substantial barrier protection as a nanocomposite [Figure c] on the low-carbon steel substrate. These nanoparticles are responsible for the barrier strength, which assists to organize and connect with the polymer chain that helps boost the film’s spreading and coverage . The efficacy of the nanocomposite was increased, demonstrated by weight loss measurements, indicating that it was adsorbed on the low-carbon steel substrate more efficiently and covered the surface-active sites and thus significantly reduced the rate of corrosion .…”
