Yittrium-supported Expanded Graphites for Hydrogen Storage |
| 초록 |
Yittrium-supported expanded graphites were prepared by mixed acid treatment of graphites. Yitrrium nanoparticles were loaded on graphite to increase the hydrogen storage capacity. The microstructure of the Yittrium-supported expanded graphites was characterized by X-ray diffraction(XRD). The elemental composition of the surface of the Yittrium-supported expanded graphites was characterized by X-ray photoelectron spectroscopy (XPS). The surface morphology was examined by scanning electron microscopy (SEM). The The specific surface area and micropore volumes of the Yittrium-supported expanded graphites were investigated using the Brunauer-Emmett-Teller (BET) and Dubinin-Radushkevich (D-R) equation. The hydrogen storage properties of the Yittrium-supported expanded graphites at 298K and 100 bars were studied using a pressure-composition-temperature apparatus. |
