Special Issue Information

Dear Colleagues,

It is well known that numerous technical products require a final surface treatment in order to comply with specific imposed requirements. The deposition of advanced functional materials and surface processing are key technologies in many industrial sectors such as corrosion protection, electronics, automotive and aerospace applications, as well as growing sectors like biotechnology, biomedical science and nanotechnology. On the other hand, deposition processes offer a variety of ways to achieve a safe and clean environment via novel green energy production and utilization, such as functionalizing the materials′ surfaces for water electrolysis reactions, fuel cell reactions, rechargeable batteries, photovoltaics, etc. Among a variety of deposition techniques, such as CVD, PVD, plasma-based processes, spraying, electroless deposition, etc., electrochemical deposition is considered a powerfuul tool for surface modification and functionalization due to the low cost of the equipment, well-established procedures, as well as relatively easy control of the coating’s thickness, morphology and properties by changing deposition parameters. Thus, electrochemical deposition at different substrates intended for different applications is the subject of this Special Issue. The Special Issuse will cover all aspects of coatings produced by electrodeposition, from our fundamental understanding of the correlation between the performance and structure obtained by controlled deposition processes to electrodeposited coatings for large-scale applications.

Yours faithfully,

To obtain highly efficient yet easily produced water-splitting cathodes, Ni-MoO2 composite coatings were electrodeposited at a Ni foam substrate with an open-pore structure, pore size of 450 µm, in a Watts-type bath. The concentration of MoO2 particles (about 100 nm) was varied, while the intensive mixing of the solution was provided by air bubbling with 0.5 L min−1. Electrodeposition was performed at different constant current densities at room temperature. The morphology and composition of the coatings were investigated by SEM and EDS. The hydrogen evolution reaction (HER) was tested in KOH of different concentrations, at several temperatures, in a three-electrode H-cell by recording polarization curves and EIS measurements. The lowest achieved HER overpotential was −158 mV at −0.5 A cm−2. Up-scaled samples, 3 × 3.3 cm2, were tested in a single zero-gap cell showing decreasing cell voltage (from 2.18 V to 2.11 V) at 0.5 A cm−2 over 5 h in 30% KOH at 70 °C with electrolyte flow rate of 58 mL min−1. Compared to pure Ni foams used as both cathode and anode under the same conditions, the cell voltage is decreased by 200 mV, showing improved electrode performance. Full article
