为探讨以煤为含碳前驱体，利用激光诱导技术制备煤基石墨烯的可能性，选择以挖金湾高挥发分烟煤、塔山低挥发分烟煤为碳源，运用激光诱导技术制备煤基石墨烯，并应用拉曼光谱（Raman）、X 射线衍射光谱（XRD）、X 射线光电子能谱（XPS）、扫描电镜（SEM）和高分辨率透射电镜（HRTEM）对原煤以及激光辐照后的产物进行表征。结果表明，经过激光辐照后，产物的Raman 图谱呈现出典型的2D 峰以及尖锐的G 峰，表明其结构有序度增强。XRD 图谱表明其（002）和（100）衍射峰变得窄而尖锐，层间距均为0.345 nm。XPS 结果表明烟煤激光辐照后sp2 的C=C 键和π—π 作用增强，这表明产物形成了sp2 网状芳香层片。通过SEM 观察到的激光辐照后样品出现分层多孔结构，同时HRTEM 结果显示出芳香条纹具有少层石墨烯特征，石墨烯层数多集中在2~10 层，且条纹间距均为0.346 nm，与XRD 得到的结果基本一致。这些分析结果表明烟煤在激光辐照后形成了煤基石墨烯。但是，受所用样品数量限制，此研究结果只是初步认识，在下一步研究中需要增加样品数量以深入研究。

In order to explore the possibility of using laser induced technology to produce coal-based graphene by using coal as carboncontaining precursor, this paper chooses high volatile bituminous coal in Wajinwan and low volatile bituminous coal in Tashan as carbon sources, and uses laser induced technology to produce coal-based graphene. Raman spectroscopy (Raman), X-ray diffraction spectroscopy (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HRTEM) were used to characterize raw coal and the products after laser irradiation. The results show that after laser irradiation, the Raman spectra of the products have a typical 2D peaks and sharp G peaks, indicating an alignment structure for the products generated. XRD results show that the diffraction peaks (002) and (100) become narrow and sharp, and the layer spacing is 0.345 nm. XPS results show that the C=C bond and π—π interaction of sp2 are enhanced after laser irradiation of bituminous coal, forming sp2 network aromatic layer. The layered porous structure of the sample after laser irradiation was observed by SEM, HRTEM results show that the aromatic fringe has the characteristics of few graphene layers, the graphene layers are mostly concentrated in 2−10 layers, and the layer spacing is 0.346 nm, which is basically consistent with the XRD results. All these data indicate that bituminous coal has been formed into coal-base graphene after laser irradiation. However, limited by the number of samples used in this paper, this study is only a preliminary understanding, and further research needs to increase the number of samples.
