| Abstract Scope |
Reduced graphene oxide (rGO) has been processed mainly by oxidative-exfoliation methods from graphite at high temperatures (> 2500 C). This presentation demonstrates a cost-effective and environmentally friendly process of pyrolysis used to synthesize sheet-like nanostructured rGO. The study includes two different biomass feedstocks of sugarcane dry leaves and onion peels. Sugarcane dry leaves are subjected to two-stage pyrolysis without any catalyst or reducing agent in far divergent temperatures to produce as-prepared and acid-treated rGOs. The sugarcane-derived rGOs have multilayered graphitic structures due to the unique ratio between G and D bands. As-prepared rGO exhibited better antibacterial activities than acid-treated rGOs. Onion peel-derived rGOs were synthesized by single-stage pyrolysis with a catalyst of ferrocene and without any catalyst, followed by conc. sulfuric acid treatment. The rGO prepared with catalyst had higher antibacterial activity than that of other. The rGO is now emerging as a tangible replacement for conventional antibiotics. |
