Hydrogen storage capacity of activated carbons from coffee wastes |
| 초록 |
In this work, activated carbons (ACs) were synthesized using KOH activation with various temperatures. X-ray diffraction (XRD) was conducted to investigate structural properties of ACs. Scanning electron microscopy (SEM) observed the morphology of ACs. The N2/77 K adsorption isotherms were used to obtain the specific surface area and pore size distribution using the Brunauer-Emmett-Teller (BET) equation and non-local density functional theory (NLDFT). Hydrogen adsorption isotherms were measured by high pressure adsorption system at 298 K and 20 bar. The results suggest that the temperature for KOH activation would affect on porosity and hydrogen uptakes. |
