Hydrogen(H2)is considered one of the most promising energy alternatives for the future due to its high energy density and green"zero"carbon properties.H2 production from water electrolysis of-fers a green and sustainable way to produce H2.Platinum(Pt)-based materials are considered to be effect-ive electrocatalysts for hydrogen evolution reaction(HER),but limited metal reserves and high prices have limited the large-scale commercialization of Pt-based catalysts;therefore,the design of low-Pt electrocata-lysts that achieve low cost and high HER performance has attracted much attention.This review summar-izes representative low-Pt catalyst synthesis strategies such as alloy strategy,strong metal support interac-tions,and single-atom strategy.The research status of low platinum electrocatalysts was systematically re-viewed.It is pointed out that the design of new low Pt catalysts,the structure-activity relationship of cata-lysts,the development of new carrier materials and the stability and reliability of catalysts in actual systems are the future research directions.
