Summary The creation of hydrogen and oxygen from water can be a paramount way to produce clean fuel through Earth‐abundant and non‐precious photoelectrochemical (solar to hydrogen production) and electrocatalysis processes. Since two decades, nickel (Ni)‐based electrocatalysts are being extensively applied as bifunctional electrocatalysts. Here, recent advances of Ni‐based catalysts in electrochemistry for water splitting application through oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) processes with evaluation parameters like dependency of the current density on the applied potential, overpotentials, and Tafel plots, etc., are brushed in brief. Various synthesis methods have also been reported with structural variations to identify the final active structure. Furthermore, based on previously published work on both OER and HER activities, disputes and outlook perspectives of Ni‐based electrolytes in the water splitting process are highlighted in succinct.
