Ultrafast H2-selective nanoporous multilayer graphene membrane prepared by confined thermal annealing

H-2 selective dense pores are generated in a graphene oxide (GO) layer by thermal-decomposition of oxygen-functional groups under high pressure. The nanoporous GO membrane shows H-2/CO2 selectivity of 12.1 and H-2 permeability of 10360 Barrer.

Automated summary

Selective dense pores for H-2 are created in a graphene oxide layer by thermally decomposing oxygen functional groups under high pressure, resulting in a nanoporous GO membrane with H-2/CO2 selectivity of 12.1 and H-2 permeability of 10360 Barrer.
