Graphene and its composites with semiconductor materials have been received highly attention in many research areas because of their unique properties. Efficient application of graphene is hindered by the lack of cost-effective synthesis methods. In this work, an economic and facile route for mass production of graphene-titanate nanocomposite has been discussed. Graphene was prepared by exfoliation of graphite powder in 40% ethanol aqueous solution. Titanate nanotubes were grown on graphene sheets by hydrothermal method, where the dispersed graphene sheets were mixed with titanate solution and then placed in autoclave and placed in oven for 16 h at 160 °C. The prepared composite was characterized by transmission electron microscope (TEM), scanning electron microscope (SEM), Fourier transforms infrared spectroscopy (FTIR), thermogravimetric analysis (TGA). All the obtained results confirmed the synthesis of graphene and its composite with titanate in highly uniform and pure form. The adsorption efficiency of the prepared composite was tested using methylene blue (MB) as a model dye. The adsorption isotherm was investigated using Freundlich and Langmuir models. The adsorption capacity of MB was 270.27 mg/g. The obtained correlation coefficients (R²) by Freundlich and Langmuir model were 0.996 and 0.973, respectively. The adsorption kinetics was investigated and discussed using different models. The thermal stability of the developed composite is improved after MB adsorption.

石墨烯及其与半导体材料的复合材料由于其独特的性能在许多研究领域受到高度关注。缺乏具有成本效益的合成方法阻碍了石墨烯的有效应用。在这项工作中，讨论了大规模生产石墨烯-钛酸酯纳米复合材料的经济且简便的途径。石墨烯是通过在 40% 乙醇水溶液中剥离石墨粉制备的。通过水热法在石墨烯片上生长钛酸盐纳米管，其中分散的石墨烯片与钛酸盐溶液混合，然后放入高压釜中，在160℃的烘箱中放置16小时。用透射电子显微镜(TEM)、扫描电子显微镜 (SEM)、傅里叶变换红外光谱 (FTIR)、热重分析(TGA)。所有获得的结果都证实了石墨烯及其与钛酸盐的复合材料以高度均匀和纯净的形式合成。使用亚甲基蓝 (MB) 作为模型染料测试制备的复合材料的吸附效率。使用 Freundlich 和 Langmuir 模型研究吸附等温线。MB的吸附容量为270.27 mg/g。Freundlich和Langmuir模型得到的相关系数（R ²）分别为0.996和0.973。使用不同的模型研究和讨论了吸附动力学。MB吸附后，开发的复合材料的热稳定性得到改善。
