Facile Synthesis Strategy from Sludge-Derived Extracellular Polymeric Substances to Nitrogen-Doped Graphene Oxide-Like Material and Quantum Dots.

ABSTRACT: Extracellular polymeric substances (EPS) are microbial aggregates derived from waste sewage sludge accumulated in sewage treatment plants, which provides natural, renewable, and abundant carbon, nitrogen, oxygen sources for the development of carbon materials to achieve the value-added utilization of waste sewage sludge resources. In this work, a nitrogen-doped graphene oxide (GO)-like material (N-GO) was simply produced using EPS as starting materials. A facile H₂O₂ oxidation-assisted method (room temperature) was developed to synthesize nitrogen-doped GO-like quantum dots (N-GOQDs) with strong tunable fluorescence from N-GO for the first time. This approach eliminates the conventional use of toxic chemicals, concentrated acids as well as expensive equipment, and str
