Emerging Graphene Derivatives and Analogues for Efficient Energy Electrocatalysis

摘要

The demand for highly efficient conversion and storage of renewable energysources calls for advanced electrocatalytic technologies. 2D graphene haslong been investigated as a versatile material platform with flexible structureand tunable surface properties for the design of efficient electrocatalysts. Inrecent years, new types of graphene derivatives and analogues keep emergingand showing great potential for highly active and selective electrocatalyticapplications. In this review, recent progresses on emerging graphene derivativesand analogues for electrocatalysis are summarized. This review startsfrom the introduction of the material requirements for efficient electrocatalysisand the advantages of 2D graphene derivatives and analogues. Thennew advances on graphene derivatives for electrocatalysis are introduced,including twisted graphene superlattices, molecular-level single-atomcatalysts, and graphene-supported dual-atom catalysts or atomic clusters.The next section deals with the emerging research directions of grapheneanalogues for electrocatalysis, including 2D metal-free materials, metallenes,2D transition metal borides (MBenes), and new design strategies of them.Finally, an overview on the development status of this field is provided, andperspectives on the future development of efficient electrocatalytic technologiesbased on 2D materials are proposed.
