Thermal and Electrochemical characteristics of naturally mixed rare earth metal oxides with graphene oxide nanocomposite |
초록 |
This study elucidates the preparation of Mischmetal oxide (Mm-oxide) - graphene oxide (GO) nanocomposite for thermal and electrochemical properties. In nanocomposite, the Mm-oxide has supportive in improving the thermal stability of GO. Decreasing the decomposition temperatures of GO occurs by broken sp2 system in earlier temperature. This result indicates that the Mm-oxide could improve the thermal stability and the decomposition reaction kinetics of GO. The determined non-isothermal activation energies are 137.61 and 107.25 kJ/mol for GO and GO-Mm-oxide composite, respectively. The current density is effectively increased for composite (1.741×10-5A) compared to GO (1.341×10-5A) and Mm-oxide (1.719×10-5A). It indicates that the nanocomposite materials have larger peak current. Therefore, the cost effective nanocomposite can be considered as a promising materials for electrochemical energy applications. |
