Abstract
Two-dimensional (2D) sheets of graphene/graphene oxide are the building blocks of a wide range of material architectures with strong application potential in energy storage and harvesting, and environmental remediation. A consistent issue with continuous 2D sheets, especially when hundreds of such 2D sheets are stacked tightly to form films and electrodes, is their low mass transport characteristics through the assembled structure. To overcome this problem, we report a sequential, two-step photochemical technique comprising nucleation of defects on 2D nanosheets of graphene/graphene oxide by long-wavelength (UVA/UVB) irradiation, followed by the growth of nanopores in H2O2-based etching trig..
