Graphene quantum dots induced porous orientation of holey graphene nanosheets for improved electrocatalytic activity

Complex electrolyte diffusion through the stacked graphene nanosheets limits their electrochemical performance. As a potential solution, this study explored the potential of nitrogen-doped graphene quantum dots (NGQDs) to induce 3D porous orientation of holey graphene oxide (hGO) nanosheets. The sizes of NGQDs and antisolvent for phase separation assisted assembly were optimized to achieve a 3D nanoporous network. This nano-network serves as a...
