1998年5月13日 · Graphite oxide (GO) and its derivatives have been studied using 13 C and 1 H NMR. NMR spectra of GO derivatives confirm the assignment of the 70 ppm line to C−OH groups and allow us to propose a new structural model for GO.
Solid-State NMR Studies of the Structure of Graphite Oxide
1996年12月19日 · Graphite oxide (GO) and its derivatives have been studied using 13 C and 1 H NMR. The 13 C NMR lines at 60, 70, and 130 ppm are assigned to C−OH, C−O−C, and >C C< groups in the bulk of the material, respectively. The >C C< double bonds are relatively stable, while C−OH groups may condense to form C−O−C (ether) linkages.

Graphite oxide (GO) and its derivatives have been studied using 13 C and 1 H NMR. The 13 C NMR lines at 60, 70, and 130 ppm are assigned to C-OH, CO -C, and >CdC< groups in the bulk of the material, respectively. The >CdC< double bonds are relatively stable, while C-OH groups may condense to form CO -C (ether) linkages.

construct structural models of noncrystalline graphite-based materials on the basis of NMR or other spectroscopic data. To address this challenge, a solid-state NMR (SSNMR)-based structural modeling approach is presented on graphite oxide (GO), which is a prominent precursor and interesting benchmark system of modified graphene.
