The Coordination Chemistry of Graphene Oxide: Interactions with Metal Ions in Water

摘要

Interactions of graphene oxide with Ag~+, Cu~(2+), Fe~(2+), Fe~(3+), and Bi~(3+) ions were studied. The minimum (threshold) ion concentrations required for the interaction with graphene oxide to occur were determined in a series of experiments. A possible model of the interaction between the metal ions and the oxygen-containing groups of graphene oxide was proposed.
