摘要:
在改进的Hummers法的基础上,提出室温制备氧化石墨(GO)的方法,制备一系列氧化石墨.考察磷酸和硫酸的体积比、反应时间及石墨尺寸对氧化石墨氧化程度的影响.采用X射线衍射仪、傅里叶变换红外光谱仪和能谱仪对产物进行表征.研究结果表明:当石墨与氧化剂高锰酸钾的质量比为1∶6,磷酸和硫酸的体积比为6∶4时,在低温处理30 min,中温处理2 h,常温处理7 d的条件下,制得的氧化石墨的氧化程度最高;所提方法的制备工艺操作简单、安全且能耗低.
Abstract:
Graphite oxide(GO)was fabricated by a room-temperature method based on improved Hummers’ method. The influence factors on the oxidation degree of GO were studied systematically, including the volume ratio of H3PO4 and H2SO4, the time under room-temperature and the size of graphite. As-prepared samples were characterized by powder X-ray diffraction, Fourier transform infrared spectrometer, and energy dispersive spectrometer. The results showed that GO with the higherest oxidation degree was obtained at such conditions: the mass ratio of graphite flakes and potassium permanganate was 1∶6; the volume ratio of H3PO4 and H2SO4 was 6∶4; the reaction time was 30 min at low temperature, 2 h at mild temperature and 7 d under room temperature. The method is considered to be simple, safe and low-energy consumption.
