Photocatalysis: Tuning the Electronic Bandgap of Graphdiyne by H‐Substitution to Promote Interfacial Charge Carrier Separation for Enhanced Photocatalytic Hydrogen Production (Adv. Funct. Mater. 29/2021)

Tuning the electronic bandgap of graphdiyne is an efficient way to construct a type II heterojunction for photocatalysis. In article number 2100994, Mohamed Nawfal Ghazzal and co-workers demonstrate enlarging the electronic bandgap of GDY via H-substitution, which promotes efficient interfacial charge separation and improves photocatalytic hydrogen evolution remarkably.
