Photocatalytic activity enhancement of PDI supermolecular via π-π action and energy level adjusting with graphene quantum dots

The separation process of photo-generated carriers and photocatalytic process. [Display omitted] •GQDs/PDI has higher photocatalytic performance than PDI under visible light.•GQDs is helpful for the electrons delocalization via π-π action with PDI.•The quantum confinement effect of GQDs helps electr...
