Graphene oxide/nanometal composite membranes for nanofiltration: synthesis, mass transport mechanism, and applications

Abstract

Graphene has promising potential in several fields because of its unique and brilliant properties, and graphene-based composites are studied for nanofiltration because of their chemical stability and thermal resistance. Nanometals are used for compositing with graphene and its derivatives, such as Ag, Au, TiO₂, and Cu. Graphene-based/nanometal membranes have remarkable performance in water treatment, antibacterial properties, and so on. In this review, we introduce the separation mechanism and fabrication method of graphene-based/nanometal composite membranes and then summarize the recent developments. Therefore, additional applications of graphene-based/nanometal composite membranes can be expected, and this paper reviews the current research trends.
