In recent years, water electrolyzers have been developed for industrial operational conditions. However, there is a significant strain on freshwater when hydrogen is produced on a large scale. Direct seawater electrolysis can rely on freshwater to produce hydrogen on a large scale. However, seawater electrolysis is very challenging due to the presence of chlorine chemistry, sluggish kinetics, and impurities, which make it more difficult. Over the years, immense efforts have been devoted to developing electrocatalysts for seawater electrolysis. The article examines general principles and various electrocatalysts to gain a deeper understanding of the current achievements in catalysts for seawater electrolysis and their prospects. Afterward, novel strategies are suggested for designing effective electrocatalysts, including protective layers for the cathode and anode in seawater electrolysis. Lastly, emerging hybrid seawater electrolysis and electrolyzer technology provide a workable alternative.

The hybrid electrolyte consists of [BMim]Cl, sulfolane and water, acting as the chemical absorbent/cocatalyst, physical absorbent and diluent respectively. With the combined Sulfinol and deep eutectic features, the electrolyte shows high CO₂ uptake rate and capacity, low viscosity and effective water activity regulation. Consequently, the CO₂RR exhibits high reaction rate and Faradaic efficiency toward CO (FE_CO). Typically, high FE_CO values of over 96% are achieved over a wide potential range from −1.8 to −2.3 V. The robustness of the electrolyte is manifested by its high FE_CO at high water content and facile regeneration by evaporation of water.

The electrocatalytic water-splitting reaction to produce ‘green hydrogen’ has a high kinetic energy barrier and hence developing a high performance electrocatalyst is very crucial and challenging. The electrocatalysts that based on NiFe catalyst system has received considerable attention because of their low cost, easy availability, increased electrochemically active surface sites compared to pure nickel and iron materials, and excellent electronic properties due to the synergistic interaction between Nickel and Iron. This review highlights the recent trends and a comprehensive analysis of the critical factors described in the literature for the design and optimization of an effective NiFe-based hydrogen evolution reaction (HER) electrocatalyst in alkaline medium. The important factors that influence the catalytic efficiency of NiFe-based electrocatalysts such as the modifications in the surface morphology, electronic structure of the catalyst, supporting material characteristics, doping with heteroatoms of metals or non-metals, heterostructuring, synthesis strategies, compositional variations, and pore structure of the catalyst are addressed from experimental and theoretical point of view. The variation of these parameters provides much exposed active sites, improved surface area, electronic conductivity, fast mass diffusion and easy desorption of hydrogen gas from the catalyst surface and stability. The NiFe-based overall water splitting, and various in situ/operando studies employed for elucidating the reaction mechanism as well as the structural evolution of the catalyst during the electrocatalytic water splitting reaction under alkaline conditions are also discussed in this review.
