(659o) A Brief Review on the Structural Modification of Graphenes for Persulfate Activation.

This brief survey discusses the structural modification of graphenes along with its efficiency as a persulfate activator in the removal of organic contaminants. Based on the existing literature, the structural modification techniques were classified into thermal and chemical modification processes. The thermal modification process primarily involves the application of heat to alter the structural properties of graphene whereas, the chemical modification process essentially introduces heteroatoms (such as N and B) and/or metal ions into the graphene structure. Remarkably, modified graphenes have a higher persulfate activation performance than unmodified graphene and pure Co₃O₄. However, several limitations on the structural modification processes have been identified and further studies are required.
