以葡萄糖为原料,采用水热法制备了单分散纳米碳球,并使用扫描电子显微镜(SEM)、透射电子显微镜(TEM)、傅里叶变换红外光谱(FT-IR)、X射线衍射(XRD)和X射线光电子能谱(XPS)对碳球的微观形貌、物相结构、表面基团和元素组成进行了分析,系统研究了葡萄糖浓度、反应釜填充度、水热温度、水热时间等参数对碳球形貌的影响。结果表明:当葡萄糖浓度为0.3mol/L,反应釜填充度为40%,水热温度为200℃,水热时间为4h时,可得到单分散的纳米碳球,碳球直径约为200nm,碳球主体以无定形结构存在,并含有少量的低程度结晶结构,其表面含有大量的含氧基团,具有较好的分散性。
Using glucose as raw material,monodisperse carbon nanospheres were prepared by hydrothermal method.The microstructure,phase structure,surface groups and elemental composition were analyzed by scanning electron microscope (SEM),transmission electron microscopy (TEM),fourier transform infrared spectroscopy (FT-IR),X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS),the influence of preparation parameters including glucose concentration,reaction kettle filling degree,hydrothermal temperature and hydrothermal time on morphology of the nanospheres were also studied.The results shown that monodisperse carbon nanospheres can be obtained with the concentration of 0.3mol/L glucose content,40% reaction kettle filling degree,200℃ hydrothermal temperature and 4h hydrothermal time.The average nanospheres diameter was about 200 nm,the subjects of the nanospheres were of amorphous structure,and contained a small amount of low degree of crystalline structure,its surface contained large amounts of oxygen containing groups,indicating good dispersion.
