A Nitrogen,Sulfur co-Doped Porphyrin-based Covalent Organic Framework as an Efficient Catalyst for Oxygen Reduction
文献摘要：
Oxygen reduction reaction(ORR) is a significant reaction for energy conversion systems(such as fuel cells,metal-air batteries,etc.).It is an urgent need to develop cheap,durable and highly-active catalysts for efficient ORR.Hence,we report a metal-free nitrogen and sulfur co-doped porphyrin-based covalent organic framework(COF) as a high-efficiency ORR catalyst[the onset potential(Eo) is 0.79 V and the half-wave potential(E1/2) is 0.70 V].The double doping of N and S atoms causes uneven charge distribution around carbon atoms,which can act as catalytic active centers,improving ORR activity.Compared with single-atom doping,double atoms doping exhibits a higher activity due to the synergistic effect between different elements.These results demonstrate that reasonable design of stable metal-free COFs with a high electrochemical activity can promote their wide applications.
