Low cost porous carbons from coffee bean wastes for electrode materials of supercapacitor |
| 초록 |
Coffee bean (CB) powder is a readily available material in daily life. The structure of coffee bean is quite similar with that of coconut shell. In this point of view, low cost porous carbons were prepared from the waste CB powder for electrode materials of supercapacitors. A carbon dioxide activation method was employed for pore development of the CB with activation time and gas feeding rate. Morphologies of activated CB (ACB) were observed by SEM and the textural properties of the ACB were measured by N2/77K adsorption isotherms. From results, ACB showed significant enhanced specific surface area and pore volumes with increasing activation time. |
