“…Transition metals such as Fe, Mn, and Ni are promising candidates due to their abundance and low cost. − To achieve specific nickel deposits, the composition of deposition solutions is controlled by adding certain additives. These additives help reduce roughness, control particle size, and achieve the desired microstructure in electrolytic nickel deposition, making the method suitable for particular applications. − In electrolytic nickel deposition, additives are also employed for the same reasons mentioned earlier, aiming to achieve a specific microstructure of the deposited nickel that is suitable for particular applications. − …”

The present work investigates the electrocatalysis of oxygen evolution (OE) on a glassy carbon electrode modified with nickel oxide nanoparticles (NPs) (nano-Ni) in an alkaline solution. The nano-Ni is electrodeposited from an acidic sulfate electrolyte containing various additives, such as glucose, glycerol, and dimethyl glyoxime. The NPs are characterized morphologically and electrochemically using scanning electron microscopy and cyclic voltammetry. The elemental composition and electronic state of the modified electrodes were analyzed using X-ray photoelectron spectroscopy. A considerable enhancement in electrocatalytic activity, depending on the additives used, is observed. The study also explores the effect of nickel oxide loading to optimize the process. The highest cathodic shift in the onset potential of the oxygen evolution reaction is achieved with nickel oxide deposited in the presence of ethylene glycol.

“…Nickel electrodeposition from ammonia-containing solutions has the advantages of high current efficiency, fast deposition rate, low energy consumption and slight corrosiveness to equipment, which is expected to solve the problems in the production and application of acidic nickel electrodeposition [16,17]. So far, research on metal and alloys electrodeposition from ammonia-containing solution, such as Zn, Cu, Co, Pd, Cd-Te, Zn-Ni, Co-Mo and Ni-Co, have been conducted and some have industrial applications [18][19][20][21][22][23][24][25]. Until now, there are still few studies about nickel electrodepositing from the ammoniacontaining solution, mainly because of the complexity of nickel species in ammonia solution and low current efficiency.…”

Composite additives have an important influence on the process of metal electrodeposition and the quality of a metal deposited layer. In this work, the additive thiourea (TU) was compounded with cetyltrimethyl ammonium chloride (CTAC), sodium dodecyl sulfate (SDS) and polyethylene glycol 20,000 (PEG20000), and their effect on the cyclic voltammetric behavior, electrochemical nucleation mechanism, crystallographic orientations and surface morphology of the nickel electrodeposition in ammoniacal solution were experimentally investigated. The results show that the introduction of composite additives resulted in a stronger cathodic polarization and increased the nucleation overpotential (NOP) values significantly, which had an important impact on forming compact and smooth nickel deposits. The chronoamperometry analysis indicated that the reduction in nickel followed the 3D progressive nucleation mechanism in the presence of composite additives at the step potential of −1.16 V and −1.18 V. Smoother and finer nickel films were found using scanning electron microscopy (SEM) images as the composite additives were used. X-ray diffraction revealed that all nickel deposit samples had the face-centered cubic structure, and five main crystal planes were displayed by the presence of composite additives in the electrolyte. Furthermore, the diffraction peaks of (111) and (200) crystal planes were slightly shifted toward lower 2θ values when thiourea was used in combination with additive CTAC or PEG20000. These results were beneficial for understanding the mechanisms and facilitating the rational design of additives for metal nickel electrodeposition.

The study focuses on the evaluation of a novel composite coating obtained from zinc salicylate (ZnSal). Ion distributions of salicylic acid and zinc(II) were surveyed at various acidities, and pH 9.5 was selected for the direct current electrodeposition of ZnSal/K2SO4 on carbon steel substrate. The surface morpholgy of the ZnSal-steel coating was revealed by scanning electron microscopy, and compact deposited films with dendrite structures (specific surface area 247 m2 g−1, type-H3 BET hysteresis loop at relative pressures from 0.4 to 1.0) could be formed within 25-min plating time. NSST was conducted, and the test duration was 120 h. Preliminary assays were employed to assess its anticorrosive performance in salt spray, and the corrosion rate of the steel plates exhibited a nonlinear relationship with the exposure time. The results showed that the ZnSal-steel had a low corrosion rate <0.11 μm h−1, thereby increasing the potential of ZnSal composites on actual carbon steel for anticorrosive coatings.
