Ion selectivity of graphene nanopores

Nature Communications, 2016
Sub-nanometer graphene nanopores are usually required to create graphene-based reverse osmosis membranes. Here, Rollings et al.show that membranes with larger pores are highly ion selective and a hundred times more permeable to potassium ions than to ...
