Highly efficient iron-nitrogen electrocatalyst derived from covalent organic polymer for oxygen reduction

We developed a cost-effective synthetic strategy via silica assistance to obtain a highly effective Fe-N-C catalysts from the rational design two-dimensional novel covalent organic polymer (COPBP-PB). The newly developed catalyst, i.e., COPBP-PB-Fe-900-SiO2, exhibits high ORR activity with an onset potential of 0.96 V and half-wave potential of 0.85 V as well as good stability.135
