Research progress on graphene-based carrier loaded with noble metals for electrocatalysis
Graphene is widely used as an electrocatalyst or electrocatalyst carriers for fuel cells because of its excellent thermal and electrical conductivity,high mechanical strength and flexibility,as well as high specific surface area and easy chemical modification.In this paper,firstly,the preparation methods of graphene-based material-supported precious metal catalysts in the past five years were reviewed.Secondly,the latest research achievements and progress of three types of graphene-based supports,namely reduced graphene oxide,doped graphene,and modified graphene,in electrocatalytic reactions were analyzed.The electrocatalytic performance of different graphene-based materials for the construction of electrocatalysts was compared,and the advantages and challenges of graphene-based carriers as electrocatalyst carriers were discussed.Finally,the development trend of graphene-based materials as electrocatalyst carriers was summarized and prospected.
