Abstract

We report an enhanced light-harvesting two-dimensional nanofluidic system based on a homogeneous graphene derivative nanocomposite membrane, and demonstrate an enhanced proton flow upon asymmetric light illumination. The maximum photocurrent is achieved by appropriately sandwiching graphene oxide quantum dots for adjusting the interlayer spacing of the membrane and reinforcing the membrane potential.
