"About 0.5 g of ground sugarcane bagasse powder mixed with 0.1 g of ferrocene was placed in a crucible and put
directly into a muffle furnace at 300 °C for 10 min under atmospheric conditions."
Instead of ferrocene, use iron II oxide?
It is possible to synthesize graphene oxide (GO) through a modified Hummers' method using biomass as a carbon source and iron(III) oxide as a catalyst in a muffle furnace. The general process involves the oxidation of biomass with strong oxidizing agents like sulfuric acid and potassium permanganate, followed by reduction to obtain GO. Iron(III) oxide can be used as a catalyst in this process. However, the specific conditions and protocols may vary, so it's essential to follow a well-established procedure and ensure safety precautions when working with strong acids and high-temperature furnaces. Additionally, you may need to consult scientific literature or a chemistry expert for precise guidance on this synthesis method.
