基于三氯化铁催化作用制备大尺寸氧化石墨烯薄膜
Preparation of Large-size Graphene Oxide Films Based on Iron(Ⅲ)Chloride Catalysis
摘要
Abstract
In order to obtain large-area graphene oxide(L-GO)films,a series of FeCl3-catalyzed L-GO films are prepared.The surface morphology and structure of L-GO films synthesized with various temperatures and times are studied by atomic force microscope(AFM), polarizing microscope(POM), Fourier transform infrared spectrometer(FTIR), and X-ray diffraction(XRD).The sheet domain area of FeCl 3-catalyzed L-GO films is 10 μm×10 μm, which increases about four times in contrast to that of GO films prepared without catalyst.By further analysis of FTIR and XRD, the formation of L-GO domains can be attributed to the new connections of the hydroxyl,carboxyl,and carbonyl groups in graphene oxide under FeCl 3catalysis.Thus,a formation model of FeCl 3-catalyzed L-GO films is proposed, which provides a new way for the preparation of large area graphene oxide films.关键词
