“…Figure 3(a) shows the XRD pattern of pristine NF, NF * , NiRu-MOFs, NiRu-MOFs-A, NiRu-MOFs-AH, and NiRu-MOFs-AO. All samples exhibit two strong peaks corresponding to the faced-centered cubic structure of nickel at 2θ = 44.5°and 51.8° [41,49,52]. More diffraction peaks appear in the lower-angle area for NiRu-MOFs, NiRu-MOFs-A, NiRu-MOFs-AH, and NiRu-MOFs-AO samples.…”

NiRu bimetallic metal–organic frameworks (NiRu-MOFs) are grown by a simple hydrothermal method on nickel foam (NF) as an the electrocatalyst for the hydrogen evolution reaction. Low-pressure plasmas of pure Ar, 95 %Ar + 5 %H2, and 95 % Ar + 5% O2 are used for the post-treatment of the NiRu-MOFs. NiRu-MOFs-AO with post-plasma treatment with 95 %Ar + 5 %O2 show the lowest overpotential of 123.3 mV at a current density of 10 mA/cm2 and a Tafel slope of 72.0 mV dec-1 in 1 M KOH electrolyte. Electrochemical impedance spectroscopy results indicate that post-plasma treatment can further reduce the charge transfer resistance. Moreover, the electric double-layer capacitance (Cdl) is calculated based on the cyclic voltammetry results, and the electrocatalyst subjected to 95 %Ar + 5 %O2 post-plasma treatment shows a 2Cdl value of 3.69 mF/cm2, suggesting a larger electrochemically active surface area after oxygen-containing-plasma treatment.

The production of hydrogen using electrolysis contributes to the development of more important renewable energy sources. Nowadays, the synthesis of alloys, which can be successfully applied as catalysts instead of precious metals, is carefully investigated. One-step electrodeposition is a surface engineering method that allows for the control of the morphology of the deposit by changing deposition parameters. It is a simple and low-cost process based on electrochemical synthesis from electrolytes, usually non-toxic crystal modifiers. In this work, a conical Ni structure on Cu foil was produced using this technique. The effect of the copper substrate on the morphology of the developed nanocones was analyzed using a Scanning Electron Microscope (SEM). Then, the catalytic performance of the synthesized coatings was carefully analyzed based on the results of a linear sweep voltammetry experiment and the measurements of their wettability and electrochemical active surface area. The proposed method of Cu treatment, including polishing with sandpapers, influenced the growth of cones and, consequently, increased the catalytic activity and active surface area of the Ni coatings in comparison to the bulk Ni sample.
