Design and Synthesis of Low Platinum Nanoelectrocatalytic Materials and Progress in Electrocatalytic Hydrogen Evolution
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.
