Abstract: Graphene is a two-dimensional carbon material with only one atom layer in thickness, with unique physical and chemical properties, such as strong mechanical properties, high thermal conductivity, large specific surface area, high light transmittance and high electron mobility, etc. Graphene oxide is a derivative present during transformation process from graphite to graphene. Compared with graphite and graphene, due to the rich functional groups between layers and at edges, graphene oxide owns property from hydrophilicity to hydrophobicity, high chemical activity, high adsorption performance and coordinated photoelectric properties, etc. As a result, graphene and graphene oxide have broad applications in the fields of machinery, optoelectronics, information technology, and catalysis, etc. With the deepening understanding of the structure and properties of graphene and graphene oxide, their preparation technology and application fields will be further expanded. Preparation technology of graphene and graphene oxide and their application in various fields are reviewed. At the same time, preparation technology and application prospect are prospected.
