Graphene-based Novel Antibacterial Nanocomposites For Water Disinfection

Antimicrobial nanomaterials have attracted increasing research interest as they provide alternative solutions for water disinfection and microbial control. Taking advantages of the unique properties of graphene nanomaterials, the present thesis reported three functionalized graphene-based novel antibacterial nanocomposites i.e. Silver/reduced graphene oxide (rGO) hydrogel, carbon dots/titanium dioxide /rGO nanocomposites, and titanium dioxide /rGO/tungsten trioxide nanocomposites. With tailor-made antibacterial properties and tunable structures, these nanocomposites were applied for fit-for-purpose water disinfection (either gravity–drive filtration or solar photocatalysis), without external energy consumption. We believed our results provided new hints to design and apply graphene-based nanocomposites for energy-efficient water disinfection.
