Graphene oxide (GO) is a unique material that has been gaining popularity as a potential alternative to carbon nanotubes due to its excellent mechanical, electrical, and thermal properties. Graphene oxide can be synthesized through various methods, such as chemical vapor deposition (CVD), sol-gel process, and electrochemical oxidation. In this blog, we will explore some common sources of graphene oxide in scientific literature and discuss their properties.

One of the most well-known sources of graphene oxide is from metal oxides, such as iron oxide (Fe2O3) and cobalt oxide (Co2O3). Iron oxide and cobalt oxide are known for their high surface area and porous structure, which makes them ideal substrates for creating graphene oxide nanowires. By depositing a thin layer of iron oxide or cobalt oxide onto a substrate, researchers can create graphene oxide films with different thicknesses, sizes, and structures.
Another source of graphene oxide is from metal-organic frameworks (MOFs), which are a class of materials consisting of metal ions embedded in organic molecules. MOFs have been used for adsorption and separation applications due to their strong binding affinity and tunable properties. Graphene oxide can be easily functionalized on the surface of MOFs by applying a hydroxide or silane coating, followed by a catalytic activity test to confirm its performance as a graphene oxide sensor or converter.
Additionally, graphene oxide can be obtained through chemical synthesis, specifically from a blend of different polymers. For example, poly(bisphenol A)(BPA) and polyvinylidene fluoride(VDF) can be mixed together to create a new type of graphene oxide that has improved mechanical properties, such as tensile strength and elasticity.
