Thermogravimetric analysis or thermal gravimetric analysis (TGA) is a method of thermal analysis in which the mass of a sample is measured over time as the temperature changes.

2020年7月29日 · Thermogravimetric analysis (TGA) indicated a higher mass loss between 150 and 230 °C. Raman spectra showed ID/IG ratios of rGO samples were higher than GO (1.36-GO; 1.45-rGO 1, 1.87-rGO 3) due to reducing GO and increasing sp 2 clusters.

Thermal stability of GO and RGO were investigated with TGA analysis. It was showed that GO decomposes with one clear step at 162 °C with total weight loss of 85.9% in Fig. 4. A significant...

2024年12月1日 · The study investigates the structural and chemical properties of graphene oxide (GO) and reduced graphene oxide (RGO) using SEM, XRD, FTIR, TGA, Raman spectroscopy, and XPS elemental analysis. The electrical conductivity of GO and RGO samples were evaluated and correlated with the structural and chemical properties.

Graphene oxide (GO) and reduced graphene oxide (rGO) nanoparticles were synthesized and characterized and their special effects on enhancing the physio-mechanical characteristics of medium...

2015年5月30日 · Graphene oxide–glycine (GO–G) nanocomposites can be used in adsorption process and other applications. In this study, we have synthesized GO–G nanocomposites. To produce this nanocomposite of GO sheets, glycine with known concentration was added to GO suspension in ethanol solvent.

2017年12月18日 · In the present investigation, GO was prepared by exfoliation of graphite using modified Hummer's method and then reduced using hydrazine hydrate (reducing agent) to produce rGO. XRD, FESEM, Raman, FTIR spectrophotometer and TGA were used for characterization of GO and rGO. XRD images reveal crystalline structure for both GO and rGO.
