Microbial oxidation of graphite by Acidithiobacillus ferrooxidans CFMI-1†
Abstract
Graphite oxide was prepared by a simple and environmentally-friendly bio-oxidation strategy using Acidithiobacillus ferrooxidans CFMI-1 bacteria. The obtained graphite oxide nanosheets have a few layers with 1.5–1.7 nm (about 3–4 layers of sheets) height and 150–900 nm size.
