CoFe2O4 nanoparticles supported on nitrogen and sulfur co-doped mesoporous carbon sphere for oxygen catalytic reactions |
| 초록 |
The development of a promising bifunctional electrocatalyst for oxygen reduction reaction and oxygen evolution reaction is highly desirable owing to the sluggish kinetics that limit these reactions. In this study, CoFe2O4 nanoparticles anchored on nitrogen and sulfur co-doped mesoporous carbon spheres (CFO/NS-MCS) were prepared by a facile pyrolysis and hydrothermal treatment process. The as-prepared CFO/NS-MCS exhibited a more promising ORR catalytic performance compared with that of commercial Pt/C. Remarkably, the CFO/NS-MCS catalysts also showed a high OER catalytic performance comparable with that of commercial RuO2 and showed better durability for oxygen catalytic reactions in an alkaline solution. The approach indicated in this research can be applied to develop high-performance electrocatalysts for practical implementation in energy storage and conversion devices. |
