The obtained material was characterized by different methods such as XRD, IR, TEM, EDS. The XRD pattern showed the successfulexfoliation of graphite with shift of diffraction maximum from 2θ=26,5 o to 10,4 o. The TEM images released the existence of graphene oxide sheet in various sizes. The sulfo group formation (–SO3H) on graphene oxide surface was confirmed by IR spectra with the appearance of characteristic picks at 1401 cm -1 và 1124 cm-1attributed to vibrations of groups S-O and S=O. Catalytic activity of GO-SO 3H was estimated by reaction of fructose conversion into 5-hydroxymethylfufural (HMF). The different reaction parameters (temperature, time, solvent), were examined. It results that highest yield reaction attained 56% at 120 oC, for 2h of reaction time and in solvent dimethyl sulfoxide (DMSO). 2018-03-21T03:07:35Z 2018-03-21T03:07:35Z 2016 Article 2588-1140 http://repository.vnu.edu.vn/handle/VNU_123/61426 other Tập 32;Số 4 application/pdf H. : ĐHQGHN |
