Abstract

Graphdiyne (GDY), a new highly π-conjugated carbon allotrope, has drawn much attention for its unique electronic, and wide application potential in many fields. The special electronic and mechanical properties of GDY offer a good platform for electronic modification, activate the high electroactivity of modified GDY. Based on that, several approaches have been proposed to modify the electronic structure of GDY, including heteroatoms doping, anchoring single metal atoms, stacking configuration control, and strain engineering. With these modification techniques, the electronic structure, bandgap, and Femi-level can be widely tuned. In addition, GDY plays a vital role in highly efficient single-atom catalysts. It can act as the ideal supporting substrate for isolated single atoms due to its outstanding electrochemical properties. Meanwhile, the latest research is found that the modified GDY can be used as the high-performance oxygen reduction reactions, oxygen evolution reactions, hydrogen evolution reactions and nitrogen reduction reactions electrocatalysts. The summary of GDY electronic modification and its application also reveals that GDY-based materials have a bright future in the field of electrochemical catalysis.
