NiO-nanoflakes grafted graphene: an excellent photocatalyst and novel nanomaterial for complete pathogen control

Abstract

The increased level of industrial pollutants in water and drug resistant pathogens are serious threat to human and aquatic life. Herein, we present the solar light induced dye removal and bactericidal properties of nickel oxide (NiO) and graphene nanoplatelets (GNPs) nanocomposites. The conducting nature of GNPs is the key factor that governs the enhanced photocatalytic and antibacterial activity. It is interestingly found that the graphene/NiO nanocomposite shows outstanding photocatalytic activity (99% degradation) as compared to NiO (34%) alone, which makes it potential candidate for depollution of dye contaminated water. In addition, the optimized amount of GNPs in graphene/NiO nanocomposite, renders it as an exceptional antibacterial material with 100% growth inhibition of pathogenic microorganisms (both Gram positive and Gram negative bacteria). Therefore, graphene/NiO nanocomposite can be an innovative material to achieve complete pathogen control alongside being an economic solution for water treatment.
