▎ 摘　　要

NOVELTY - The method involves placing (210) a graphene sheet on a fixed structure. The carbon atoms are disrupted (220) in the graphene sheet. The disrupted carbon atoms are removed (230) to create nano pores in the graphene sheet with elliptical pore geometry. The pore geometry of the nanoporous graphene sheet separates hydrogen gas from hydrogen gas mixture. USE - Method for creating nanoporous graphene sheet. ADVANTAGE - The method achieves high throughput of hydrogen from the pores. DESCRIPTION OF DRAWING(S) - The drawing shows the flowchart illustrating the method for creating nanoporous graphene sheet. Step for placing a graphene sheet on a fixed structure (210) Step for disrupting carbon atoms in the graphene sheet (220) Step for removing disrupted carbon atoms to create nano pores in graphene sheet with elliptical pore geometry (230) Step for generating pore (240)
