文摘
- •
Undoped and nitrogen-doped graphene quantum dots (N-GQDs) were synthesized
- •
Photoelectrochemical properties of N-GQD sensitized ZnO nanorods was investigated
- •
Sensitized nanorods demonstrated superior photoconversion efficiency and incident photon to current conversion efficiency
- •
N-GQDs exhibited better photoelectrochemical behavior due to strong chemical bonding and lower interfacial resistance.
