The article discusses the electrodeposition of mesoporous nickel films from sulfate solutions using lyotropic liquid crystal templates. These films exhibit high mesoporosity with an average pore size of 7.5 nm and a density of approximately 644 pores per micrometer. The electrodes' morphology and microstructure, characterized by field-emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM), show a rough surface with excellent adhesion to the substrate. The study highlights the role of magnetic fields in enhancing the efficiency of the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) through Lorentz forces, magnetohydrodynamics (MHD), and periodic stray magnetic fields. Mesoporous nickel electrodes displayed superior electrocatalytic activity, outperforming bulk nickel electrodes by up to 200% in HER current density. The research also explores capillary rise in porous coatings, emphasizing its significance in practical applications. Chronoamperometry tests revealed the stability and performance of mesoporous nickel electrodes under the influence of magnetohydrodynamic effects, showcasing enhanced current densities in the presence of a magnetic field. The findings underscore the importance of surface roughness and hydrophilicity in mitigating bubble formation and improving the overall efficiency of hydrogen gas production.
