Abstract

Abstract : NiO-nanoflakes grafted graphene provides exciting solution to decontaminate dyes polluted water alongside being a novel bactericidal nanomaterial. Abstract : The increased levels of industrial pollutants in water and of drug-resistant pathogens more generally are a 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 nanoplatelet (GNP) nanocomposites. The conducting nature of GNPs is the key factor that accounts for the enhanced photocatalytic and antibacterial activity. Remarkably, the graphene/NiO nanocomposite shows outstanding photocatalytic activity (99% degradation) as compared to NiO (34%) alone, which makes it a potential candidate for the depollution of dye-contaminated water. In addition, the optimized amount of GNPs in the graphene/NiO nanocomposite renders it an exceptional antibacterial material, producing 100% growth inhibition of pathogenic microorganisms (both Gram-positive and Gram-negative bacteria). Therefore, the graphene/NiO nanocomposite can be an innovative material to achieve complete pathogen control, alongside being an economic solution for water treatment.
