Effect of Additives on Hydrogen Evolution and Absorption during Zn Electrodeposition Investigated by EQCM

Influence of Polymer Coating on the Electrode Properties of Fe₃O₄/Carbon Nano-fiber Composite in Alkaline Electrolyte

“…The inhibition of hydrogen evolution by PEG addition has been reported previously for zinc electrode. 21 Similarly in the present Fe 3 O 4 /CNF case, PEG may inhibit the adsorption of dissociated hydrogen.…”

Electrodeposition of Alloys Coatings from Electrolytic Baths Prepared by Recovery of Exhausted Batteries for Corrosion Protection

“…The Figure 4 shows the morphology of the deposit obtained potentiostatically at -1.2 V from the base solution (S0). The SEM image shows that the deposit is comprised of hexagonal plates with pyramidal clusters grouped into nodules of several sizes, as is normal for pure zinc electrodeposits [37]. The EDS analysis (inset on Figure 4) showed the presence of zinc as the predominant element in the coating.…”

“…The instability observed in the electrodepositions carried out with S0 solution, particularly at -1.6 V, may be attributed to hydrogen evolution. In a study on the effect of additives on the hydrogen evolution reaction during Zn electrodeposition, Song et al [37] suggested that PEG acts as an inhibitor of hydrogen absorption in the electrodeposited Zn. The characterization of the coating obtained potentiostatically was performed by measurements of Scan Electronic Microscopy (SEM), Energy Dispersion Spectroscopy (EDS) and X Ray Diffraction (XRD).…”

Effect of Organic Additives on Electrodeposition of Tin From Acid Sulfate Solution

“…It is an irreversibly hydrolyzed form of collagen, wherein the hydrolysis results in the reduction of protein fibrils into smaller peptides, which have broad molecular weight ranges. A gelatin colloid is often used as an inhibitor in the electrodeposition of metals; namely, copper [23], tin [7], silver [24], and zinc [25]. Sodium gluconate is a non-corrosive, non-toxic, biodegradable, and renewable additive to electroplating baths and can be successfully used for the electrodeposition of heavy metals and alloys [15,16,18,[26][27][28].…”
