I'm preparing graphene oxide using sugarcane bagasse powder. Method of preparation is: take 0.5g sugarcane bagasse in china dish and add 0.1g of ferrocene as an oxidizing agent. Mixed them and then put into muffle furnace at 300 °C for 10 mint.
Dear Sibgha Batool , sugarcane bagasse powder is mainly composed by cellulose, so you have fundamentally C, H and O compounds, that can burn at these conditions. Review your method, you need a carbon source (the bagasse powder) and oxygen from the air (or provided as a gas flow), the carbon source must be burned to remove the unwanted components and retain just the C and O that form the graphene oxide.

Hope it helps.
