| 제목 | Preparation graphene oxide muffin and its electrochemical application |
| 초록 | In this study, graphene oxide web are prepared by sequential experimental method of homogeneous dispersion in water and freeze drying of graphene oxide solutions. Benefiting from the freeze drying, graphene oxide muffin (GOM) demonstrated hierarchical structure with increased surface area and pore volume. Moreover, GOM are successfully turned into reduced graphene oxide web with photo-thermal treatment within 5 seconds of application of plasma. As-synthesized photo-thermally reduced graphene oxide muffin (PrGOM) are applied as supercapacitor. For the comparison,chemically reduced reduced graphene oxide muffin (CrGOM) is prepared as a supercapacitor material. Consequently, PrGOM showed 4-fold higher specific capacitance (210 F/g) compared to CrGOM. This increased electrochemical performance of PrGOM is owing to the preservation of micro pores and web-like structure without degradation, which mainly occurred in chemical reduction process. |
