论文摘要
进行了一项比较研究，进行了氧化石墨烯碳纳米管纳米复合材料和ZnO纳米颗粒之间的比较研究，以研究它们在若丹明B染料降解中的能力。我们利用改良的悍马方法来制备氧化石墨烯纳米片。此外，石墨烯碳纳米管已从GO和多壁碳纳米管与羟基合成。使用水热法来制造来自ZnO纳米颗粒和石墨烯 - 碳纳米管的氧化氧化氧化石墨烯纳米管纳米复合材料。在X射线衍射（XRD）表征期间，在同一相角中发现了ZnO和氧化氧化石墨烯碳纳米管纳米复合材料的所有显着峰。此外，最终的纳米复合材料还以场发射扫描电子显微镜（FESEM）和能量色散X射线光谱（EDS）为特征。最后，从染料降解试验中，很明显，与ZnO纳米颗粒相比，氧化氧化物石墨烯 - 碳纳米管纳米复合材料表现出优异的染料去除能力。
A comparative study between zinc oxide graphene-carbon nanotubes nanocomposite and ZnO nanoparticles was carried out to investigate their abilities in the degradation of Rhodamine B dye. We utilized the Modified Hummer method to prepare the graphene oxide nanosheet. Moreover, graphene-carbon nanotubes had been synthesized from GO and multi-walled carbon nanotubes with a hydroxyl group. The hydrothermal method was employed to fabricate the zinc oxide graphene-carbon nanotubes nanocomposite from ZnO nanoparticles and graphene-carbon nanotubes. During the characterization by X-ray Diffraction (XRD), all the significant peaks of ZnO and zinc oxide graphene-carbon nanotubes nanocomposite were found in the same phase angle. In addition, the final nanocomposite was also characterized by Field Emission Scanning Electron Microscope (FESEM) and Energy Dispersive X-ray Spectroscopy (EDS). Finally, from the dye degradation test, it was apparent that zinc oxide graphene-carbon nanotubes nanocomposite showed superior dye removal ability compared to the ZnO nanoparticles.
