Abstract
In recent years, the sustainable utilization of waste materials has become a significant research area due to environmental concerns and resource scarcity. Graphene oxide nanoparticles (GONPs) are regarded as one of the most important materials due to their capacity to serve as a potentially scalable precursor to graphene and, more recently, as the most promising substance in biomedical research. This study successfully explores the synthesis of GONPs using recovered carbon black (rCB) derived from waste tires. The structural, morphological and antibacterial properties of the synthesised GONPs in this study were highlighted. The intensity ratio (ID/IG) from Raman spectroscopy analysis, obtained at 0.82, with FTIR spectral results shows the functional groups of hydroxyl, carboxyl and epoxy, similar to GO synthesised from pure graphite. TEM analysis showed that the surface morphology of the GONPs contains nanoparticles with a size of 44.95 nm. Despite using waste material, GONPs exhibited potential antibacterial activity towards the gram-positive and gram-negative bacteria tested in this study. The data presented here are novel and show the possibility of GONP synthesis from waste tires as a future cost-effective antibacterial agent.
期刊介绍：
Nano-Structures & Nano-Objects is a new journal devoted to all aspects of the synthesis and the properties of this new flourishing domain. The journal is devoted to novel architectures at the nano-level with an emphasis on new synthesis and characterization methods. The journal is focused on the objects rather than on their applications. However, the research for new applications of original nano-structures & nano-objects in various fields such as nano-electronics, energy conversion, catalysis, drug delivery and nano-medicine is also welcome. The scope of Nano-Structures & Nano-Objects involves: -Metal and alloy nanoparticles with complex nanostructures such as shape control, core-shell and dumbells -Oxide nanoparticles and nanostructures, with complex oxide/metal, oxide/surface and oxide /organic interfaces -Inorganic semi-conducting nanoparticles (quantum dots) with an emphasis on new phases, structures, shapes and complexity -Nanostructures involving molecular inorganic species such as nanoparticles of coordination compounds, molecular magnets, spin transition nanoparticles etc. or organic nano-objects, in particular for molecular electronics -Nanostructured materials such as nano-MOFs and nano-zeolites -Hetero-junctions between molecules and nano-objects, between different nano-objects & nanostructures or between nano-objects & nanostructures and surfaces -Methods of characterization specific of the nano size or adapted for the nano size such as X-ray and neutron scattering, light scattering, NMR, Raman, Plasmonics, near field microscopies, various TEM and SEM techniques, magnetic studies, etc .
