Detailed thermal reduction analyses of graphene oxide via in-situ TEM/EELS studies

We report an in-depth study of the reduction graphene oxide (GO) by in-situ thermal transmission electron microscopy (TEM) analysis. In-situ heating high-resolution TEM (HRTEM) imaging and energy-loss spectroscopy (EELS) measurements have been combined to identify transformations different oxygen functional groups, desorption physisorbed chemisorbed water graphitization as a function temperature in range from 70 up 1200{\deg}C. A model for general removal OFGs is proposed based on chemical physical parameters that monitored. All this unique information provides detailed roadmap behaviour GO at extended temperature. This not only interest understand process but also critical relevance response applications when exposed effects.
