摘要
Electrocatalytic water splitting into hydrogen is one of the most promising methods to deal with global energy crisis and greenhouse effect. However, the conversion efficiency is greatly limited by the sluggish charge transfer, and severe agglomeration of catalysts. Graphdiyne (GDY), consisting of both sp- and sp2-hybridized carbon atoms in a 2D planar structure, possesses distinct chemical and physical properties, like direct bandgap, natural uniform pores and superior conductivity, which makes GDY an ideal support to inhibit the agglomeration of the catalyst and accelerate the charge transfer. In this review, various graphdiyne-supported electrocatalysts used to splitting water into hydrogen and oxygen, are described. The future challenges of GDY as catalyst support are also outlined. Such a comprehensive summary not only provides a profound understanding of GDY-supported catalysts for electrochemical energy conversion, but also opens up promising channels for catalysts design.
