제목 Synthesis of graphene oxides and carbon spheres for applications in the removal of water pollutants
초록 Herein, we report the fabrication of different carbon materials, either bare or ornamented with metallic nanoparticles. Graphene oxide (GO) and carbon spheres (CS) were prepared separately followed by synthesis of graphene- metal nanocomposites and graphene-carbon sphere hybrid aerogel. Graphene-based metal and metal oxide composites were synthesized hydrothermally using NaBH4 as a reducing agent and sodium sorbate as a stabilizer. Graphene-carbon sphere hybrid aerogel decorated with silver nanoparticles was then synthesized by induced reduction and gelation of a mixture of GO and silver doped CS in an oil bath. The synthesized materials have been characterized by various spectroscopic analyses. The inactivation of E. coli, the catalytic degradation of 4-nitrophenol, and the adsorption of heavy metals and dye were examined. Disinfection, catalytic and adsorption ability of CNMs showed promising efficacy towards a variety of water contaminants.
