Abstract Transition metal compounds (TMCs) are potentially fruitful substitutes for noble metals electrocatalytic splitting of water due to their intrinsic activity, modifiable morphology, tunable electronic structure and earth‐abundance. The combination TMCs with graphene improves the dispersion loaded catalysts, providing more catalytic active sites, enhancing conductivity hybrids, affording accelerated charge‐transfer kinetics, minimizing catalyst bleaching, aggregation, sintering under harsh reaction conditions. Additionally, incorporation into modulates centers because synergistic interaction between them, thereby improving performance. This review paper focuses on recent progress made in designing different graphene‐transition metal‐based materials that can be used hydrogen evolution (HER), oxygen (OER), overall (OWS). In‐situ characterization methodologies DFT calculations facilitate development discussed elaborately. Finally, advancements graphene‐supported transition use a functional electrolyzer have been explored. In conclusion, few specific recommendations about current challenges related widespread production effective HER/OER electrocatalysts electrolysis.

Constructing transition metal multiphase composites can improve the electrocatalytic efficiency of (sea)water splitting via interfacial interaction between adjacent active sites. Herein, self-supporting NimSn-FeOx heterostructure is in situ grown on nickel foam (NF) through a corrosion engineering approach, which displays abundant dendritic array structures, endowing material with sites and high area. The control introducing Fe3+ sulfur precursors effectively trigger phase transiting from Ni3S2 to Ni9S8, generating more S vacancies, could reduce reaction energy barrier performance. Simultaneously, presence Fe–S bonding at sulfide/oxide interface brings strong electronic interaction, enables tuning adsorption intermediates accelerates catalytic kinetics. As result, Ni9S8–FeOx/NF-Fe8.0 catalyst presents low overpotentials 159 mV 190 for oxygen evolution 100 mA cm–2 under 1 M KOH solution simulated seawater conditions, respectively. overall water incorporating as both anode cathode provides potential 1.707 V 1.794 cm–2. This research furnishes an efficient strategy toward design advanced heterogeneous splitting.
