Abstract Controlling the adverse effects of global warming on human communities requires reducing carbon dioxide emissions and developing clean energy resources. Fossil fuel overuse damages environment raises sustainability concerns. As a resource‐rich element, cobalt oxide hybrids have attracted considerable attention as low‐priced eco‐friendly electrocatalysts. Alkaline solutions disperse Co 3 O 4 easily despite its highly stable nature, which arises from reverse spinel structures Co. Metal oxides, nickel foam, polymeric frameworks, nanotubes been successfully served to combine with constructions for improving electrocatalytic performance. To date, no comprehensive study has systematically investigated relation between hybrid's physicochemical‐electronic aspects catalytic features. This review mainly focuses material design, fabrication, morphology, structural characteristics, electroactivity, considering critical factors towards practical applications. The economic impacts their expected contribution large‐scale utilizations are also demonstrated. Moreover, this research discusses synergistic crucial electrochemical parameters sustainable production over ‐based hybrids. Finally, some beneficial conclusive suggestions made based emerging real‐world application. Future in field aiming at technologies can effectively benefit findings report.

The reliance on fossil fuels has led to numerous environmental challenges, highlighting the urgent need for alternative energy sources that minimize contamination and promote eco-friendliness. In this context, hydrogen (H2) emerges as a promising fuel due its zero-carbon emissions. Within various methods H2 production, electrochemical water splitting (EWS) stands out viable approach. Traditionally, noble metals, such platinum iridium, have been employed electrocatalysts efficiently facilitate evolution reaction (HER) in desired electrolytes (such alkaline). Recently, research focused use of Prussian blue (PB) an innovative electrocatalyst material EWS. Herein, we developed PB-based HER alkaline medium. comprising PB combined with phosphorus exhibited impressive properties, achieving minimal overpotential 103 mV at current density 10 mA/cm2 maintaining durability over 20 h, along extended performance. This composition considerable promise potential option conversion systems, which can aid future sustainability initiatives.
