我合成了石墨烯,对原料石墨和产物石墨烯做了XRD测试。在用jade分析的时候,产物石墨烯匹配了Graphite-2H的标准卡片,原料石墨则相较Graphite-2H所有峰偏左一点(小了0.5°左右)。请问这算是合成成功了吗?Graphite-2H是指石墨烯吗? 展开 0评论 +关注 共3个回答 她的混世大魔,给排水工程师 2019-05-18回答 2H...
The quality of graphite oxide, graphene oxide and graphene can be determined by studying the XRD, FTIR, SEM, TEM and Raman spectra. Multiple graphene layers are obtained, when, before being subjected to chemical cleaning and ultrasound treatment, in an N2 environment at a feverish temperature, ...
The broadening effect of stacking disorder in hexagonal graphite is found experimentally by XRD to be identical to that of stacking faults in hexagonal-closed-packing(HCP) structure,which has obvious selective broadening effect.The Langford's method for dealing with the twofold broadening effects of ...
According to the XRD patterns (Figure 1), mainly hexagonal structure (2H) existed in natural graphite with a little rhombohedral structure (3R) and did not change after expansion. At the base of XRD analysis (Figure 1), the oxidants were intercalated into natural graphite and formed expansible...
Nanodiamond (111) and Graphite (100) peaks stay close to each other in the XRD spectra, located at 2h 5 44.0u and 2h 5 43.8u with 60.05u variation due to inherent strain in the sample, respectively36,37. The sharp peak located around 2h 5 43.8u in Figure 5(a) is in good ...
To investigate the effect of introduced iron on graphitization, samples were detected by XRD and Raman. As displayed in Fig. 1(a), (0 0 2) and (1 0 1) crystal planes of the graphite 2H (PDF#75-1621) at 26.2° and 43.9° respectively can be Conclusions In this paper, a kind of ...
