Due to the structural and performance disparities between graphene and graphene-like carbon materials, they exhibit distinctpotential applications. Appropriate characterizations are important to analyze the properties of graphene materials and to guide their research. In this paper, four materials labeled as single-layer graphene (G1), few-layer graphene (G2), multilayer graphene (G3), andindustrial-grade multilayer graphene (G4) were studied, and their physical and chemical structures were characterized by Raman spectroscopy, X - Ray Diffraction ( XRD), Scanning Electron Microscopy ( SEM), Transmission Electron Microscope ( TEM), AtomicForce Microscopy (AFM) and N2 adsorption/ desorption methods. The means of characterization, data analysis and mutual verification ofeach characterization result were discussed. The results show that G1 has a relatively low number of layers with ID / IG = 0.88. Validationthrough TEM, AFM, and XRD confirms an actual number of 10-20 layers, a specific surface area of 564.03 m2 / g , and the typical characteristics of graphene, placing it within the category of graphene. In contrast, G2-G4 have more than 100 layers with ID / IG = 0.07-0.18.The specific surface area of G2-G4 is 30- 50 m2 / g. Combining structural and morphological results, these materials are classified asthe graphene-like category. This study provides reference and guidance for the analysis and quality assessment of graphene materials.
