Pt supported antimony-functionalized graphitic nanoplatelets for the Oxygen Reduction Reaction and Hydrogen Evolution reaction |
| 초록 |
Antimony-functionalized graphitic nanoplatelets (SbGnPs) are made as a supporter by the mechanochemical reaction between graphite and metalloid Sb. Pt electrocatalysts supported on SbGnPs are prepared for oxygen reduction reaction (ORR) and hydrogen evolution reaction (HER). The resultant Pt@SbGnP electrocatalysts show higher ORR and HER activity and stability than the commercial Pt/C catalysts in acidic condition due to the interaction between Pt and antimony doped at the edge. Therefore, the active sites of the Pt@SbGnPs is significantly increased, revealing superior catalytic activity with lower overpotentials. The Pt@SbGnP is the potentially possibility to use as electrocatalysts for ORR and HER in the future. |
