Reduced graphene (G) was prepared by chemically reducing graphene oxide (GO). For the first time, the resulting G was functionalized by 1,6-diaminohexane and decorated with silver nanoparticles (AgNPs). The resulting G and modified G were characterized by X-ray diffraction (XRD), nuclear magnetic resonance (NMR), infrared (FTIR) spectroscopies, and high resolution transmission electron microscopy (HRTEM). The 1,6-diaminohexane-graphene structure was ascertained from the NMR and FTIR data. AgNPs were identified with various sizes within the graphene matrix. The resulting hybrid material was used as an effective antimicrobial contact catalyst for disinfecting water from Total Coliform and Fecal Coliform bacteria. A triple action in this respect was achieved from graphene, 1,6-diaminohexane, and AgNPs without observed release of silver that causes toxicity.
