Hydrogen is considered as the promising energy carrier to substitute traditional fossil fuel,due to its cleanli-ness,renewability and high energy density.Water electrol-ysis is a simple and convenient technology for hydrogen production.The efficiency of water electrolysis for hydrogen production is limited by the electrocatalytic performances on hydrogen evolution reaction(HER)and oxygen evolution reaction(OER).The exorbitant Pt-and Ir-/Ru-based elec-trocatalysts as optimal HER and OER electrocatalysts,respectively,restrict water electrolysis development.Recently,non-precious metal-based high-entropy electro-catalysts have exhibited excellent electrocatalytic activities and long-term stabilities for water electrolysis,as promising precious catalyst candidates.Therefore,the construction of the high-entropy electrocatalysts is vital to water electrolysis industry.Electrodeposition technology is an efficient method for the preparation of high-entropy electrocatalysts due to its simple,fast,energy-saving and environmental-friendly advantages.Multi-component co-precipitation facilely occurs during the electroredox in electrodeposition processes.High-entropy alloys,oxides,(oxy)hydroxides,phosphides and phosphorus sulfide oxides have been suc-cessfully prepared by galvanostatic,potentiostatic elec-trodeposition,cyclic voltammetry,pulse,nanodroplet-mediated and cathodic plasma electrodeposition techniques.Hence,introduction of the development of high-entropy electrocatalysts synthesized by electrodeposition technology is significant to researchers and industries.Challenges and outlooks are also concluded to boost the industrial applica-tion of electrodeposition in water electrolysis and other energy conversion areas.
