Applications of Graphene in Hydrogen Evolution Electrocatalyst
Developing hydrogen energy is an important direction in the future.Industrialized scale electrolysis of water for hydrogen production requires the use of low-cost hydrogen evolution electrocatalyst materials to reduce its overpotential.graphene has shown broad application prospects in hydrogen evolution electrocatalyst materials due to its large specific surface area,excellent conductivity,good stability,adjustable electronic structure,and easy modification of structure and surface state.This article provides a detailed analysis of the mechanism of graphene application in hydrogen evolution electrocatalysis.based on different mechanisms,graphene-based hydrogen evolution electrocatalyst materials were classified and their latest research progress was reviewed.Finally,the future development direction of graphene-based hydrogen evolution electrocatalytic materials was prospected。
