Defect‐Rich Graphdiyne Quantum Dots as Efficient Electron‐Donors for Hydrogen Generation (Adv. Energy Mater. 30/2024)

Hydrogen Generation In article number 2401547, Mohamed Nawfal Ghazzal and co-workers highlight the role of oxygen defects and the quantum size effect on the photophysical properties and light harvesting ability of graphdiyne. The defect-rich graphdiyne quantum behaves as a chromophore, absorbing a wide range of solar energy and injecting photoexcited electrons into TiO2. The composite exhibits higher photocatalytic H2 production while using a lower amount of sacrificial electron donors.
