Abstract The preparation of atom-thick porous lattice hosting Å-scale pores is attractive to achieve a large ion-ion selectivity in combination with ion flux. Graphene film an ideal selective layer for this if high-precision can be incorporated, however, it challenging avoid larger non-selective at the tail-end pore size distribution which reduces selectivity. Herein, we develop strategy overcome challenge using electrochemical repair that successfully masks large-area graphene. 10-nm-thick...
Membranes based on atom-thin, porous single-layer graphene (PG) have shown attractive performance for diverse separation applications, especially gas and carbon capture. However, despite a decade of research, scalable synthesis PG membranes has remained under question. This is mainly because the literature resorts to complicated expensive methods that yield small limited reproducibility. Herein, we introduce several interventions significantly reduce membrane cost, allow uniform pore...
