As traditional energy structures transition to new sources, hydrogen is receiving significant research attention owing to its potential as a clean energy source. The most significant problem with electrochemical hydrogen evolution is the need for highly efficient catalysts to drive the overpotential required to generate hydrogen gas by electrolyzing water. Experiments have shown that the addition of appropriate materials can reduce the energy required for hydrogen production by electrolysis of water and enable it to play a greater catalytic role in these evolution reactions. Therefore, more complex material compositions are required to obtain these high-performance materials. This study investigates the preparation of hydrogen production catalysts for cathodes. First, rod-like NiMoO4/NiMo is grown on NF (Nickel Foam) using a hydrothermal method. This is used as a core framework, and it provides a higher specific surface area and electron transfer channels. Next, spherical NiS is generated on the NF/NiMo4/NiMo, thus ultimately achieving efficient electrochemical hydrogen evolution. The NF/NiMo4/NiMo@NiS material exhibits a remarkably low overpotential of only 36 mV for the hydrogen evolution reaction (HER) at a current density of 10 mA·cm−2 in a potassium hydroxide solution, indicating its potential use in energy-related applications for HER processes.

Controlling the adverse effects of global warming on human communities requires reducing carbon dioxide emissions and developing clean energy resources. Fossil fuel overuse damages the environment and raises sustainability concerns. As a resource‐rich element, cobalt oxide hybrids have attracted considerable attention as low‐priced and eco‐friendly electrocatalysts. Alkaline solutions disperse Co3O4 easily despite its highly stable nature, which arises from the reverse spinel structures of Co. Metal oxides, nickel foam, polymeric frameworks, and carbon nanotubes have been successfully served to combine with the Co3O4 constructions for improving the electrocatalytic performance. To date, no comprehensive study has systematically investigated the relation between the cobalt oxide hybrid's physicochemical‐electronic aspects and its catalytic features. This review mainly focuses on material design, fabrication, morphology, structural characteristics, and electroactivity, considering the critical factors towards practical applications. The economic impacts of the constructions and their expected contribution to large‐scale utilizations are also demonstrated. Moreover, this research discusses the synergistic effects of crucial electrochemical parameters on sustainable energy production over the Co3O4‐based hybrids. Finally, some beneficial conclusive suggestions are made based on emerging factors for real‐world application. Future research in the field aiming at developing sustainable and clean energy production technologies can effectively benefit from the findings of this report.
