- •
High concentration yellow GQDs and TiO2 nanotubes were achieved by a simple and green method.
- •
High quantum yield GQDs enhanced the photodegradation capacity of TiO2 nanotube.
- •
The catalytic performance of GQDs/TiO2 depends on the GQDs loading.
- •
The improved photocatalytic activity of GQDs/TiO2 was attributed to three aspects.
