Design of Fe, N co-doped multi-walled carbon nanotubes for efficient oxygen reduction. Issue 92 (4th November 2020) - Du, Peng
Abstract : Fe and N co-doped multi-walled carbon nanotubes (Fe, N-MWCNTs) are designed and fabricated to efficiently catalyze the oxygen reduction reaction (ORR). Abstract : Unique Fe and N co-doped multi-walled carbon nanotubes are designed to efficiently catalyze the oxygen reduction reaction (ORR). The preparation processes involve surface functionalization, subsequent wet impregnation and final thermal fixation of Fe–N x species. The catalyst achieved outstanding alkaline ORR performance with a very positive half-wave potential (∼0.91 V). Theoretical calculations show that the carbon layer below the active Fe–N x sites is beneficial to the ORR.
