Facile and gram-scale synthesis of graphitic carbon nitride materials with high electrocatalytic activity for fuel cells |
| 초록 |
A key issue in the commercialization of fuel cell technology is a replacing Pt-based catalyst with lower-cost, non-precious metal catalysts. The recently developed cost effective and highly stable metal-free catalysts are including nitrogen doped carbons, graphitic carbon nitride based hybrids, and 2D grapheme based materials. Among them, graphitic carbon nitride has proven to be effective as catalyst for various applications such as photocatalysis and fuel cells, because of it has higher nitrogen content and more active reaction sites than other N-carbon materials to serve as a feasible metal-free ORR electrocatalyst. Here we report facile and gram-scale production of graphitic carbon nitride-CNF hybrid composite, via a simple process without high-pressure, high-temperature reactor. The resulting composite material exhibited competitive ORR catalytic activity and stability compared to a commercial Pt/C catalyst. |
